14 CFR Part 39
[Docket No. 2002-NE-33-AD; Amendment 39-13939; AD 2005-01-14]
RIN 2120-AA64
Airworthiness Directives; Bombardier-Rotax GmbH Type 912 F, 912
S, and 914 F Series Reciprocating Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD) for Bombardier-Rotax GmbH Type 912 F, 912 S, and 914 F series
reciprocating engines. That AD currently requires venting of the
lubrication system and inspection of the valve train on all engines.
That AD also requires venting of the lubrication system of all engines
on which the lubrication system has been opened, and any engine on
which the propeller has been rotated one full turn in the wrong
direction. This AD requires similar actions, and also requires removing
the existing part number oil dipstick from service and installing a new
oil dipstick. This AD results from the need to clarify the mandated
procedures for inspections and venting. This AD also results from the
manufacturer discovering that under certain circumstances, the oil
level in the oil tank can fall below the minimum level required to
sustain proper engine lubrication. We are issuing this AD to prevent
damage to the engine valve train due to inadequate venting of the
lubrication system, which can result in an in-flight engine failure and
forced landing.
DATES: This AD becomes effective February 15, 2005. The Director of the
Federal Register previously approved the incorporation by reference of
certain publications as listed in the regulations as of October 28,
2002 (67 FR 65033, October 23, 2002).
ADDRESSES: You can get the service information identified in this AD

FOR FURTHER INFORMATION CONTACT: Richard Woldan, Aerospace Engineer,
Engine Certification Office, FAA, Engine and Propeller Directorate, 12
New England Executive Park; telephone (781) 238-7136; fax (781) 238-
7199.
SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR Part 39
with a proposed airworthiness directive (AD) to supersede AD 2002-21-
16. The proposed AD applies to Bombardier-Rotax GmbH Type 912 F, 912 S,
and 914 F series reciprocating engines. We published the proposed AD in
the Federal Register on August 12, 2004 (69 FR 49829). That action
proposed to do the following:
At the next oil change, or within 100 hours TIS after the
effective date of the AD, whichever is later, remove the oil dipstick,
part number (P/N) 956150, from service, and install a serviceable
dipstick that has a different P/N.
Before the next engine start for engines with 50 hours or
less time-in-service (TIS) on the effective date of the AD, since the
engine had the oil system opened, or the oil was changed using other
than specified procedures, or the propeller was rotated more than one
turn in the wrong direction of rotation, inspect for valve train
damage, proper venting of the lubrication system and inspect for the
correct venting of the hydraulic valve tappets.
Thereafter, for all engines, properly vent the lubrication
system before starting the engine, after any of the following:
Initial installation of a new or overhauled engine;
Opening the oil system;
Changing the oil using improper procedures;
The propeller was rotated more than one turn in the wrong
direction of rotation, allowing air to be ingested into the valve train
components.
Examining the AD Docket
You may examine the AD Docket (including any comments and service
information), by appointment, between 8 a.m. and 4:30 p.m., Monday
through Friday, except Federal holidays. See ADDRESSES for the
location.
Comments
We provided the public the opportunity to participate in the
development of this AD. We received no comments on the proposal or on
the determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.
Costs of Compliance
There are about 624 Bombardier-Rotax GmbH Type 912 F, 912 S, and
914 F series reciprocating engines of the affected design in the
worldwide fleet. We estimate that 282 engines installed on aircraft of
U.S. registry will be affected by this AD. We also estimate that it
will take about one work hour per engine to perform one oil system
inspection and venting, and that the average labor rate is $65 per work
hour. Required parts will cost about $0.85 per engine. Based on these
figures, we estimate the total cost of the AD to U.S. operators to be
$18,570.

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 summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary by
sending a request to us at the address listed under ADDRESSES. Include
``AD Docket No. 2002-NE-33-AD'' in your request.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the Federal Aviation Administration amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by removing Amendment 39-12923 (67 FR
65033, October 23, 2002) and by adding a new airworthiness directive,
Amendment 39-13939, to read as follows:
2005-01-14 Bombardier-Rotax GmbH: Amendment 39-13939. Docket No.
2002-NE-33-AD. Supersedes AD 2002-21-16 (Amendment 39-12923).
Effective Date
(a) This airworthiness directive (AD) becomes effective February
15, 2005.
Affected ADs
(b) This AD supersedes AD 2002-21-16.
Applicability
(c) This AD applies to Bombardier-Rotax GmbH 912 F, 912 S, and
914 F series reciprocating engines. These engines are installed on,

Unsafe Condition
(d) This AD results from the manufacturer discovering that under
certain circumstances, the oil level in the oil tank can fall below
the minimum level required to sustain proper engine lubrication. The
actions specified in this AD are intended to prevent damage to the
engine valve train due to inadequate venting of the lubrication
system, which can result in an in-flight engine failure and forced
