DEPARTMENT OF TRANSPORTATION
Federal Aviation Administration
14 CFR Part 39
[Docket No. 2002-CE-26-AD]
RIN 2120-AA64
Airworthiness Directives; Raytheon Aircraft Company Model 1900D
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: This document proposes to adopt a new airworthiness directive
(AD) that would apply to certain Raytheon Model 1900D airplanes. This
proposed AD would require you to accomplish a one-time inspection for
missing rivets on certain areas of the airplane and, if necessary,
install rivets. This proposed AD is the result of Raytheon identifying
several instances of missing rivets on these airplanes. The actions
specified by this proposed AD are intended to detect and correct an
understrength condition in the fuselage, which could result in the
failure of the fuselage. Such failure could lead to loss of control of
the airplane in flight.
DATES: The Federal Aviation Administration (FAA) must receive any
comments on this proposed rule on or before March 3, 2003.
ADDRESSES: Submit comments to FAA, Central Region, Office of the
Regional Counsel, Attention: Rules Docket No. 2002-CE-26-AD, 901
Locust, Room 506, Kansas City, Missouri 64106. You may view any
comments at this location between 8 a.m. and 4 p.m., Monday through
Friday, except Federal holidays. You may also send comments

regulatory, economic, environmental, and energy aspects of this
proposed rule that might suggest a need to modify the rule. You may
view all comments we receive before and after the closing date of the
rule in the Rules Docket. We will file a report in the Rules Docket
that summarizes each contact we have with the public that concerns the
substantive parts of this proposed AD.
How can I be sure FAA receives my comment? If you want FAA to
acknowledge the receipt of your mailed comments, you must include a
self-addressed, stamped postcard. On the postcard, write ``Comments to
Docket No. 2002-CE-26-AD.'' We will date stamp and mail the postcard
back to you.
Discussion
What events have caused this proposed AD? The FAA has received
reports from Raytheon that during manufacturing rivets were not
installed in the following locations:
[sbull] Lower frame forward of the airstair door below the pilot's
floor;
[sbull] Forward of the upper forward corner of the airstair door;
[sbull] The bulkhead forward of the cargo door below floor level;
and
[sbull] The lower fuselage panel aft of the wing.
These rivets must be installed for the fuselage to carry the
ultimate design load. Without the rivets, these areas are
understrength.
What are the consequences if the condition is not corrected? The
understrength condition in the fuselage could result in the failure of
the fuselage. Such failure could lead to loss of control of the
airplane in flight.
Is there service information that applies to this subject? Raytheon
has issued Service Bulletin No. SB 53-3046, Issued: February 2002.
What are the provisions of this service information? The service
bulletin includes procedures for:
[sbull] Inspecting for missing rivets; and
[sbull] Installing rivets.
The FAA's Determination and an Explanation of the Provisions of This
Proposed AD
What has FAA decided? After examining the circumstances and
reviewing all available information related to the incidents described
above, we have determined that:
[sbull] The unsafe condition referenced in this document exists or
could develop on other Raytheon Model 1900D airplanes of the same type
design;
[sbull] The actions specified in the previously-referenced service
information should be accomplished on the affected airplanes; and
[sbull] AD action should be taken in order to correct this unsafe
condition.
What would this proposed AD require? This proposed AD would require
you to incorporate the actions in the previously-referenced service
bulletin.
Cost Impact
How many airplanes would this proposed AD impact? We estimate that
this proposed AD affects 370 airplanes in the U.S. registry.
[[Page 79892]]
What would be the cost impact of this proposed AD on owners/
operators of the affected airplanes? We estimate the following costs to
accomplish the proposed inspection:
----------------------------------------------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
8 workhours x $60 per hour = $480.. No parts required.... $480 $480 x 370 = $177,600
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to accomplish any necessary rivet
installation that would be required based on the results of the
proposed inspection. We have no way of determining the number of
airplanes that may need such installation:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
15 workhours x $60 per hour = $900...... $25 $925
------------------------------------------------------------------------
Compliance Time of This Proposed AD
What would be the compliance time of this proposed AD? The
compliance time of this proposed AD is within the next 1,200 hours
time-in-service (TIS) or 1 year after the effective date of this AD,
whichever occurs first.
Why is the compliance time of this proposed AD presented in both
hours TIS and calendar time? The usage of these airplanes varies widely
because operators or lessors are cycling these airplanes between
airplane storage and flight operations. However, the unsafe condition
on these airplanes is not a result of the number of times the airplane
is operated. Airplane operation varies among operators. For example,
one operator may utilize the airplane 50 hours TIS in 3 months, while
it may take another operator 12 months or more to accumulate 50 hours
TIS. For this reason, FAA has determined that the compliance time of
the proposed AD should be specified in both hours TIS and calendar time
in order to ensure this condition is not allowed to go uncorrected over
time.
Regulatory Impact
Would this proposed AD impact various entities? The regulations
proposed herein would 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. Therefore, it is determined that this
proposed rule would not have federalism implications under Executive
Order 13132.
Would this proposed AD involve a significant rule or regulatory
action? For the reasons discussed above, I certify that this proposed
action (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) if
promulgated, 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. A copy of the draft regulatory
evaluation prepared for this action has been placed in the Rules
Docket. A copy of it may be obtained by contacting the Rules Docket at
the location provided under the caption ADDRESSES.
