Airworthiness Directives; Various Aircraft Equipped With
Honeywell Primus II RNZ-850( )/-851( ) Integrated Navigation Units

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

[[Page 15332]]

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding an existing airworthiness directive
(AD) that applies to certain Honeywell Primus II RNZ-850( )/-851( )
integrated navigation units (INUs). As one alternative for compliance,
the existing AD provides for a one-time inspection to determine whether
a certain modification has been installed on the Honeywell Primus II
NV-850 navigation receiver module (NRM), which is part of the INU. In
lieu of accomplishing this inspection, and for aircraft found to have
an affected NRM, that AD provides for revising the aircraft flight
manual to include new limitations for instrument landing system
approaches. That AD also requires an inspection to determine whether
certain other modifications have been done on the NRM; and doing
related investigative, corrective, and other specified actions, as
applicable; as well as further modifications to address additional
anomalies. This AD extends the compliance time for a certain inspection
and associated actions. This AD also revises the applicability to
include additional affected INUs. This AD results from reports
indicating that erroneous localizer and glideslope indications have
occurred on certain aircraft equipped with the subject INUs. We are
issuing this AD to ensure that the flightcrew has accurate localizer
and glideslope deviation indications. An erroneous localizer or
glideslope deviation indication could lead to the aircraft making an
approach off the localizer, which could result in impact with an
obstacle or terrain.

DATES: This AD becomes effective May 3, 2010.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of May 3, 2010.
On December 1, 2006 (71 FR 62907, October 27, 2006), the Director
of the Federal Register approved the incorporation by reference of
Honeywell Alert Service Bulletin 7510100-34-A0035, dated July 11, 2003;
and Honeywell Service Bulletin 7510100-34-0037, dated July 8, 2004.

SUPPLEMENTARY INFORMATION:

Discussion

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that supersedes AD 2006-22-05, Amendment
39-14802 (71 FR 62907, October 27, 2006). The existing AD applies to
various aircraft equipped with certain Honeywell Primus II RNZ-850( )/-
851( ) integrated navigation units (INUs). That NPRM was published in
the Federal Register on May 19, 2008 (73 FR 28751). That NPRM proposed
to continue to provide, as one alternative for compliance, a one-time
inspection to determine whether a certain modification has been
installed on the Honeywell Primus II NV-850 navigation receiver module
(NRM), which is part of the INU. In lieu of accomplishing this
inspection, and for aircraft found to have an affected NRM, that NPRM
proposed to continue to provide for revising the aircraft flight manual
to include new limitations for instrument landing system approaches.
That NPRM proposed to continue to require an inspection to determine
whether certain other modifications have been done on the NRM; and
doing related investigative, corrective, and other specified actions,
as applicable; as well as further modifications to address additional
anomalies. That NPRM also proposed to extend the compliance time for a
certain inspection and associated actions and to revise the
applicability to include additional affected INUs.

Comments

We provided the public the opportunity to participate in the
development of this AD. We have considered the comments that have been
received on the NPRM.

Request for Credit for Actions Performed in Compliance With Previous
Service Information

Two commenters, ExpressJet Airlines and Honeywell, request that
credit be given for actions performed in compliance with previous
service information.
ExpressJet Airlines states that paragraph (l) of the NPRM calls for
an inspection on any INU that is not identified in Table 2 of the NPRM.
However, the NPRM does not take into account the units which have
already been driven to Mod T status by Honeywell Service Bulletin
7510100-34-0037, dated July 8, 2004. ExpressJet requests that
compliance with Honeywell Service Bulletin 7510100-34-0037 be
considered as an alternative to the inspections required in paragraph
(l) of the NPRM.
Honeywell also commented on the same issue. Honeywell states that
it is concerned that many airplanes have been inspected and verified to
be compliant with AD 2006-22-05. Honeywell asks the FAA to clarify
whether the intent of the NPRM was to require that all affected
operators re-inspect their airplanes. Honeywell also asks if the FAA
can make a note under the compliance section to advise operators who
actually complied with AD 2006-22-05 and verified their radios have
modification AS and the new part number installed that they were
already compliant with the new AD.
We agree to provide clarification for both ExpressJet Airlines' and
Honeywell's comments. Paragraph (l) of this AD applies only to any INUs
that are not listed in Table 2 of this AD (which is the same list as
Table 1 of AD 2006-22-05). In addition, if operators have previously
inspected INUs that are not listed in Table 2 and have accomplished the
applicable actions specified in paragraph (l) of this AD, then those
operators are already in compliance with paragraph (l) of this AD.
According to paragraph (e) of this AD, the actions are required within
the specified compliance time, unless already accomplished. Honeywell
Service Bulletin 7510100-34-0037 only addresses the localizer fix.
However, this AD requires that the glide slope be fixed in addition to
the localizer. We will not consider compliance with Honeywell Service
Bulletin 7510100-34-0037 as an alternative to the inspections required
in paragraph (l) of the NPRM. No changes have been made to the final
rule.

[[Page 15333]]

Request To Remove Reference to Specific Revision of Service Information

Honeywell requests that the FAA remove the reference to Revision 1,
dated January 21, 2003, of the Honeywell Technical Newsletter (TNL)
A23-3850-001 and simply reference the ``current revision.'' The TNL is
currently at Revision 6. Based on the release of this new AD, Honeywell
states that it plans to update the TNL with current information and
clarify how to interpret the AD. Honeywell states that it cannot
release the update until the new AD is released.
We disagree with Honeywell's request to refer to the ``current
revision'' of the TNL. The NPRM did not require the Honeywell TNL, but
did require Honeywell Alert Service Bulletin 7510100-34-A0035, dated
July 11, 2003; and Honeywell Service Bulletin 7510100-34-0037, dated
July 8, 2004; as the appropriate sources of service information to
accomplish the required actions in this AD. Honeywell provided the TNL
as a tool to communicate with its customers regarding this technical
issue. We included the TNL in Note 3 of the NPRM for reference only. To
avoid confusion, we have removed Note 3 of the NPRM, which referred to
this TNL.

Request To Revise Paragraph (j) of the NPRM

Honeywell recommends wording changes to paragraph (j) of the NPRM
to remove the sentence ``If Mod T is installed, no further action is
required by this paragraph.''
We agree to remove the sentence ``If Mod T is installed, no further
action is required by this paragraph'' from paragraph (j) of the NPRM.
Although Honeywell provides no justification for this wording change,
we agree that making this change provides further clarification. Doing
Mod T repairs only the localizer in accordance with Honeywell Service
Bulletin 7510100-34-0037, dated July 8, 2004. However, the intent of
this AD is to require that the glide slope and the localizer be
serviced. Doing Mod T repairs the localizer in accordance with
Honeywell Service Bulletin 7510100-34-0037, dated July 8, 2004. The
glide slope is addressed by accomplishing the actions in Honeywell
Alert Service Bulletin 7510100-34-A0034, dated February 28, 2003.
Honeywell Alert Service Bulletin 7510100-34-A0035, dated July 11, 2003,
does not address the localizer; it provides instructions for changing
the part number after the glide slope is repaired. The glide slope and
the localizer repairs are accomplished independent from each other in
different Honeywell service bulletins.
Therefore, we have revised paragraph (j) of this AD by adding the
text ``* * * (which relates to the glide slope fix) * * *'' to the
sentence that begins ``If Mod L, N, P, or R is installed * * *'' and
adding ``if Mod T is not installed (which relates to the localizer
fix), within 30 months after December 1, 2006, do all applicable
related investigative, corrective, and other specified actions in
accordance with the Accomplishment Instructions * * *'' in that same
sentence (before ``Honeywell Service Bulletin 7510100-34-0037, dated
July 8, 2004''). We made this change to clarify that Honeywell Service
Bulletin 7510100-34-0037, dated July 8, 2004, addresses the localizer
fix. This change does not increase the scope of this AD.

Request To Include Additional Service Information

Honeywell requests that we add Honeywell Alert Service Bulletin
7510134-34-A0017, dated July 11, 2003, to Table 1 in the NPRM.
We agree to include Honeywell Alert Service Bulletin 7510134-34-
A0017, dated July 11, 2003, in Table 1 of this final rule to maintain
consistency because the other service bulletins included in Table 1 of
this AD were issued in pairs. Honeywell Alert Service Bulletin 7510100-
34-A0034, dated February 28, 2003, was paired with Honeywell Alert
Service Bulletin 7510134-34-A0016, Revision 001, dated March 4, 2003.
Honeywell Service Bulletin 7510100-34-0037, dated July 8, 2004, was
paired with Honeywell Service Bulletin 7510134-34-0018, dated July 8,
2004. Adding Honeywell Alert Service Bulletin 7510134-A0017, does not
change any requirements of this AD, because Honeywell Alert Service
Bulletin 7510134-34-A0017 is a prerequisite to Honeywell Alert Service
Bulletin 7510100-34-A0035, dated July 11, 2003, and Honeywell Alert
Service Bulletin 7510100-34-A0035 refers to Honeywell Alert Service
Bulletin 7510134-34-A0017.
We contacted Honeywell for more information about the technical
content of Honeywell Alert Service Bulletin 7510134-34-A0017, dated
July 11, 2003. Honeywell Alert Service Bulletin 7510100-34-A0035, dated
July 11, 2003, references Honeywell Alert Service Bulletin 7510134-34-
A0017, dated July 11, 2003, as a source of service information on the
new part numbers assigned after performing Honeywell Alert Service
Bulletin 7510100-34-A0034, dated February 28, 2003. We have added
Honeywell Alert Service Bulletin 7510134-34-A0017, dated July 11, 2003,
to Table 1 of this AD. This does not increase the financial burden on
operators, nor does it increase the scope of the AD.

Request To Add Part Numbers

Honeywell requests that we revise paragraph (l) of the NPRM to list
part numbers 7510134-611, -631, -701, and -731; which are parts of the
Honeywell Primus II RNZ-850( )/-851( ) INU after modification; to the
inspection to determine whether Mod L, N, P, R, or T is installed.
We agree to provide clarification. We have revised paragraphs (l),
(l)(1), (l)(2), and (l)(3) of this AD to specify the NRM part numbers
7510134-611, -631, -701, and -731 instead of the modification level.
Paragraphs (l)(1) and (l)(2) of this AD correctly specify which
combination of part number and modification level meets the technical
requirements of the modification. We have determined that these changes
will neither increase the economic burden on any operator nor increase
the scope of the AD.

Explanation of Changes to This AD

We have changed the product identification line in the body of this
AD to specify the design approval holder of the affected appliance
rather than ``various aircraft.''

Conclusion

We have carefully reviewed the available data, including the
comments that have been received, and determined that air safety and
the public interest require adopting the AD with the changes described
previously. We have determined that these changes will neither increase
the economic burden on any operator nor increase the scope of the AD.

Explanation of Change to Costs of Compliance

After the NPRM was issued, we reviewed the figures we have used
over the past several years to calculate AD costs to operators. To
account for various inflationary costs in the airline industry, we find
it necessary to increase the labor rate used in these calculations from
$80 per work hour to $85 per work hour. The cost impact information,
below, reflects this increase in the specified hourly labor rate.

Costs of Compliance

There are about 3,063 aircraft of the affected design in the
worldwide fleet. The following table provides the estimated costs for
U.S. operators to

[[Page 15334]]

comply with this AD. The manufacturer states that it will supply
required parts to existing customers at no cost.

Estimated Costs
--------------------------------------------------------------------------------------------------------------------------------------------------------
Average
Action Work hours labor rate Parts Cost per Number of U.S.-registered Fleet cost
per hour aircraft aircraft
--------------------------------------------------------------------------------------------------------------------------------------------------------
Inspection for NRM modification level.. 1 $85 $0 $85 Up to 1,500............... Up to $127,500.
AFM revision........................... 1 85 0 85 Up to 1,500............... Up to 127,500.
Modification (to Mod T configuration).. 1 85 0 85 Up to 1,500............... Up to 127,500.
--------------------------------------------------------------------------------------------------------------------------------------------------------

The cost impact figures discussed above are based on assumptions
that no operator has yet accomplished any of the proposed actions
specified in this final rule, and that no operator would accomplish
those actions in the future if this AD were not adopted. We have been
advised, however, that the actions have already been done on some
affected airplanes. Therefore, the future economic cost impact of this
rule on U.S. operators is expected to be less than the cost impact
figures indicated above.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
subtitle VII, part A, subpart III, section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.

Regulatory Findings

We have determined that this AD will not have federalism
implications under Executive Order 13132. This AD will not have a
substantial direct effect on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866;
(2) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.

Note 1: This AD applies to Honeywell Primus II RNZ-850( )/-851(
) INUs installed on any aircraft, regardless of whether the aircraft
has been otherwise modified, altered, or repaired in the area
subject to the requirements of this AD. For aircraft that have been
modified, altered, or repaired so that the performance of the
requirements of this AD is affected, the owner/operator must request
approval for an alternative method of compliance in accordance with
paragraph (o) of this AD. The request should include an assessment
of the effect of the modification, alteration, or repair on the
unsafe condition addressed by this AD; and, if the unsafe condition
has not been eliminated, the request should include specific
proposed actions to address it.

Unsafe Condition

(d) This AD results from reports indicating that erroneous
localizer and glideslope indications have occurred on certain
aircraft equipped with the subject INUs. We are issuing this AD to
ensure that the flightcrew has accurate localizer and glideslope
deviation indications. An erroneous localizer or glideslope
deviation indication could lead to the aircraft making an approach
off the localizer, which could result in impact with an obstacle or
terrain.

Compliance

(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.

Restatement of Certain Requirements of AD 2006-22-05

Compliance Time for Action

(f) For any INU identified in Table 2 of this AD: Within 5 days
after March 11, 2003 (the effective date of AD 2003-04-06, Amendment
39-13054, which was superseded by AD 2006-22-05), accomplish the
requirements of either paragraph (g) or (h) of this AD. After
December 1, 2006 (the effective date of AD 2006-22-05), only
accomplishing the requirements of paragraph (g) of this AD is
acceptable for compliance with this paragraph.

------------------------------------------------------------------------

Inspection To Determine Part Number

(g) For any INU identified in Table 2 of this AD: Perform a one-
time general visual inspection of the modification plate for the
Honeywell Primus II NV-850 Navigation Receiver Module (NRM); part
number 7510134-811, -831, -901, or -931; which is part of the
Honeywell Primus II RNZ-850( )/-851( ) INU; to determine if Mod L
has been installed. The modification plate is located on the bottom
of the Honeywell Primus II RNZ-850( )/-851( ) INU, is labeled NV-
850, and contains the part number and serial number for the
Honeywell Primus II NV-850 NRM. If Mod T is installed, the letter
will be blacked out. The Honeywell service bulletins listed in Table
1 of this AD are acceptable sources of service information for the
inspection required by this paragraph.
(1) If Mod L is installed, before further flight, do paragraph
(h) or (j) of this AD. After December 1, 2006, only accomplishment
of paragraph (j) is acceptable for compliance with this paragraph.

Note 2: For the purposes of this AD, a general visual
inspection is defined as: ``A visual examination of an interior or
exterior area, installation, or assembly to detect obvious damage,
failure, or irregularity. This level of inspection is made from
within touching distance unless otherwise specified. A mirror may be
necessary to enhance visual access to all exposed surfaces in the
inspection area. This level of inspection is made under normally
available lighting conditions such as daylight, hangar lighting,
flashlight, or droplight and may require removal or opening of
access panels or doors. Stands, ladders, or platforms may be
required to gain proximity to the area being checked.''

Aircraft Flight Manual (AFM) Revision

(h) For aircraft having an INU identified in Table 2 of this AD:
Revise the Limitations section of the AFM to include the following
statements (which may be accomplished by inserting a copy of the AD
into the AFM):

``FLIGHT LIMITATIONS

When crossing the Outer Marker on glideslope, the altitude must
be verified with the value on the published procedure.
For aircraft with a single operating glideslope receiver, the
approach may be flown using normal procedures no lower than
Localizer Only Minimum Descent Altitude (MDA).
For aircraft with two operating glideslope receivers, the
aircraft may be flown to the published minimums for the approach
using normal procedures if both glideslope receivers are tuned to
the approach and both crew members are monitoring the approach using
independent data and displays.''

Parts Installation

(i) For aircraft having an INU identified in Table 2 of this AD:
As of March 11, 2003, no person may install a Honeywell Primus II
NV-850 NRM on which Mod L has been installed, on the Honeywell
Primus II RNZ-850( )/-851( ) INU of any aircraft, unless paragraph
(h) or (j) of this AD is accomplished. As of December 1, 2006, only
accomplishment of paragraph (j) is acceptable for compliance with
this paragraph.

Inspection To Determine Modification Level of NRM

(j) For any INU identified in Table 2 of this AD on which Mod L
was found to be installed during the inspection required by
paragraph (g) of this AD, or for aircraft on which paragraph (h) of
this AD was accomplished: Within 30 months after December 1, 2006,
do an inspection of the modification plate on the Honeywell Primus
II NV-850 NRM; part number 7510134-811, -831, -901, or -931; which
is part of the Honeywell Primus II RNZ-850( )/-851( ) INU; to
determine if Mod L, N, P, R, or T is installed. The modification
plate located on the bottom of the Honeywell Primus II RNZ-850( )/-
851( ) INU is labeled NV-850, and contains the part number and
serial number for the Honeywell Primus II NV-850 NRM. If Mod L, N,
P, R, or T is installed, the corresponding letter on the
modification plate will be blacked out. Honeywell Alert Service
Bulletin 7510100-34-A0035, dated July 11, 2003; and Honeywell
Service Bulletin 7510100-34-0037, dated July 8, 2004; are acceptable
sources of service information for this inspection. If Mod L, N, P,
or R is installed (which relates to the glide slope fix), within 30
months after December 1, 2006, do all applicable related
investigative, corrective, and other specified actions, in
accordance with the Accomplishment Instructions of Honeywell Alert
Service Bulletin 7510100-34-A0035, dated July 11, 2003; and if Mod T
is not installed (which relates to the localizer fix), within 30
months after December 1, 2006, do all applicable related
investigative, corrective, and other specified actions, in
accordance with the Accomplishment Instructions of Honeywell Service
