ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires changing the emergency open doors procedure by incorporation of a temporary revision into the FAAapproved airplane flight manual (AFM) for all airplanes. This AD also requires replacement of the passenger door retaining bracket with an improved design retaining bracket for certain airplanes. This AD was prompted by several reports of the rear passenger door departing the airplane in flight. We are issuing this AD to change the emergency open doors procedure and retrofit the rear passenger door retaining bracket, which if not corrected could result in the rear passenger door departing the airplane in flight. DATES: This AD is effective January 11, 2011. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of January 11, 2011.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to the specified products. That NPRM published in the Federal Register on August 25, 2010 (75 FR 52292). That NPRM proposed to require a retrofit of the rear passenger door retaining bracket for certain airplanes. The NPRM also proposed to change the emergency open doors procedure by incorporation of a temporary revision into the FAAapproved AFM for all airplanes. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal and the FAA’s response to each comment. Request To Shorten the Compliance Time Robert Hasiak fully supported this AD action and stated that a door falling out of the sky over the general public is a safety hazard and that the sooner this is fixed, the safer we will be. We infer that the commenter wants us to shorten the compliance time from the proposed 6 months. The FAA does not agree that 6 months is an unreasonable compliance time to address this situation. This 6-month compliance time is consistent with the service bulletin in that the time for compliance closely coincides with June 11, 2011 (the compliance time in the service bulletin). It also coincides with the appropriate risk level the FAA, the Austro Control Group (ACG), and European Aviation Safety Agency (EASA) agreed with. The FAA has determined that the actions of this AD and the compliance time address the unsafe condition in the interim until further analysis is done by Diamond Aircraft Industries GmbH (Diamond), EASA, and the FAA. We are not changing the AD based on this comment. PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 Request To Revise the Airplane Flight Manual Procedures David Wood stated that the door departure while the aircraft is in flight happens when someone realizes the door is only being retained by the safety latch and then tries to close the door completely. This causes the safety latch to disengage and the door to depart the aircraft. The commenter suggests the following: ‘‘DO NOT TRY TO CLOSE THE DOOR ON TAKEOFF ROLL, CLIMB, CRUISE, DESCENT, OR UNTIL VERY SLOW LANDING ROLL.’’ We infer that he wants the language added to the emergency open doors procedure in the AFM. We agree with the commenter’s assessment of the unsafe condition and the need to revise the emergency open doors procedure. However, we disagree on the suggested language. Diamond has ¨ issued Temporary Revision TR–MAM 40–428, dated April 30, 2010. This revision changes the emergency open doors procedure to ‘‘Land at the next suitable airfield’’ when it is determined the rear door is unlocked. The revision also adds a warning to not attempt to lock the rear door in flight. The FAA has determined the action in this AD of adding the temporary revision to the AFM addresses the unsafe condition. We are not changing the AD based on this comment. Request To Include the Model DA42 Villis Ositis of the Thielert Engine Owners Group commented that the Model DA 42 has the same door design and the same unsafe condition. He recommended that the AD also apply to the Model DA 42. The FAA has discussed the potential of the rear door departing the Model DA 42 aircraft in flight with ACG, EASA, and Diamond. The FAA has determined the actions of this AD and the compliance time address the unsafe condition in the interim for the Model DA 40. Further analysis is being done for the Model DA 42. We may consider future rulemaking action on the Model DA 42 based on that analysis. We are not changing the AD based on this comment. Request To Disconnect the Front Canopy Latch Sensor From the Door Open Indicator Villis Ositis of the Thielert Engine Owners Group commented that the door open annunciation illuminates regardless whether it is the front canopy or the rear door that is not latched. The commenter states that since these aircraft do not have air conditioning it is common practice to taxi with the E:\FR\FM\07DER1.SGM 07DER1 Federal Register / Vol. 75, No. 234 / Tuesday, December 7, 2010 / Rules and Regulations canopy in the partially open setting, illuminating the door open annunciation. As a result, the pilot ignores the annunciation and is unaware that the rear door might not be properly latched. The commenter also states that passengers that have not been trained in the use of the doors may not be able to identify an incorrect latch position. To correct the problem, the commenter suggests the wiring be modified to remove the front canopy latch sensor from the door open annunciation. In this proposed configuration the door open annunciation would only illuminate when the rear door was not properly latched and alert the pilot to the unsafe condition. The FAA does not agree nor disagree with the proposed comment. Rather, the FAA is investigating this matter with ACG, EASA, and Diamond. Diamond is now planning a design and flight test review to determine the overall safety issues with regard to this recommendation, which could take a few months to complete. In the interim, the FAA has determined that the actions of this AD address the unsafe condition until further analysis is done. The FAA may consider further rulemaking action based on the evaluation. We are not changing the AD based on this comment. Conclusion We reviewed the relevant data, considered the comments received, and 75869 determined that air safety and the public interest require adopting the AD as proposed—except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. Costs of Compliance We estimate that this AD affects 699 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Parts cost Revise the AFM (all airplanes) ...................... Retrofit the passenger door retaining bracket (428 airplanes). .5 work-hour × $85 per hour = $42.50 ......... 2 work-hours × $85 per hour = $170.00 ...... Not Applicable .. $75.00 .............. 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.

The MCAI describes the unsafe condition as: SUMMARY: In accordance with design regulation, the THSA [trimmable horizontal stabilizer actuator] has a failsafe design. Its upper attachment to the aeroplane has two load paths, a Primary Load Path (PLP) and a Secondary Load Path (SLP), which is only engaged in case of PLP failure. Following the design intent, engagement of the SLP leads to jam the THSA, indicating the failure of the PLP. Tests carried out under the loads-measured during representative flights have demonstrated that, when the SLP is engaged, it does not systematically jam the THSA. In E:\FR\FM\07DER1.SGM 07DER1

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD requires changing the emergency open 
doors procedure by incorporation of a temporary revision into the FAA-
approved airplane flight manual (AFM) for all airplanes. This AD also 
requires replacement of the passenger door retaining bracket with an 
improved design retaining bracket for certain airplanes. This AD was 
prompted by several reports of the rear passenger door departing the 
airplane in flight. We are issuing this AD to change the emergency open 
doors procedure and retrofit the rear passenger door retaining bracket, 
which if not corrected could result in the rear passenger door 
departing the airplane in flight.

DATES: This AD is effective January 11, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of January 11, 
2011.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an airworthiness directive (AD) that would apply to 
the specified products. That NPRM published in the Federal Register on 
August 25, 2010 (75 FR 52292). That NPRM proposed to require a retrofit 
of the rear passenger door retaining bracket for certain airplanes. The 
NPRM also proposed to change the emergency open doors procedure by 
incorporation of a temporary revision into the FAA-approved AFM for all 
airplanes.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
and the FAA's response to each comment.

Request To Shorten the Compliance Time

    Robert Hasiak fully supported this AD action and stated that a door 
falling out of the sky over the general public is a safety hazard and 
that the sooner this is fixed, the safer we will be. We infer that the 
commenter wants us to shorten the compliance time from the proposed 6 
months.
    The FAA does not agree that 6 months is an unreasonable compliance 
time to address this situation. This 6-month compliance time is 
consistent with the service bulletin in that the time for compliance 
closely coincides with June 11, 2011 (the compliance time in the 
service bulletin). It also coincides with the appropriate risk level 
the FAA, the Austro Control Group (ACG), and European Aviation Safety 
Agency (EASA) agreed with. The FAA has determined that the actions of 
this AD and the compliance time address the unsafe condition in the 
interim until further analysis is done by Diamond Aircraft Industries 
GmbH (Diamond), EASA, and the FAA. We are not changing the AD based on 
this comment.

Request To Revise the Airplane Flight Manual Procedures

    David Wood stated that the door departure while the aircraft is in 
flight happens when someone realizes the door is only being retained by 
the safety latch and then tries to close the door completely. This 
causes the safety latch to disengage and the door to depart the 
aircraft. The commenter suggests the following: ``DO NOT TRY TO CLOSE 
THE DOOR ON TAKEOFF ROLL, CLIMB, CRUISE, DESCENT, OR UNTIL VERY SLOW 
LANDING ROLL.'' We infer that he wants the language added to the 
emergency open doors procedure in the AFM.
    We agree with the commenter's assessment of the unsafe condition 
and the need to revise the emergency open doors procedure. However, we 
disagree on the suggested language. Diamond has issued Temporary 
Revision TR-M[Auml]M 40-428, dated April 30, 2010. This revision 
changes the emergency open doors procedure to ``Land at the next 
suitable airfield'' when it is determined the rear door is unlocked. 
The revision also adds a warning to not attempt to lock the rear door 
in flight. The FAA has determined the action in this AD of adding the 
temporary revision to the AFM addresses the unsafe condition. We are 
not changing the AD based on this comment.

Request To Include the Model DA42

    Villis Ositis of the Thielert Engine Owners Group commented that 
the Model DA 42 has the same door design and the same unsafe condition. 
He recommended that the AD also apply to the Model DA 42.
    The FAA has discussed the potential of the rear door departing the 
Model DA 42 aircraft in flight with ACG, EASA, and Diamond. The FAA has 
determined the actions of this AD and the compliance time address the 
unsafe condition in the interim for the Model DA 40. Further analysis 
is being done for the Model DA 42. We may consider future rulemaking 
action on the Model DA 42 based on that analysis. We are not changing 
the AD based on this comment.

Request To Disconnect the Front Canopy Latch Sensor From the Door Open 
Indicator

    Villis Ositis of the Thielert Engine Owners Group commented that 
the door open annunciation illuminates regardless whether it is the 
front canopy or the rear door that is not latched. The commenter states 
that since these aircraft do not have air conditioning it is common 
practice to taxi with the

[[Page 75869]]

canopy in the partially open setting, illuminating the door open 
annunciation. As a result, the pilot ignores the annunciation and is 
unaware that the rear door might not be properly latched. The commenter 
also states that passengers that have not been trained in the use of 
the doors may not be able to identify an incorrect latch position.
    To correct the problem, the commenter suggests the wiring be 
modified to remove the front canopy latch sensor from the door open 
annunciation. In this proposed configuration the door open annunciation 
would only illuminate when the rear door was not properly latched and 
alert the pilot to the unsafe condition.
    The FAA does not agree nor disagree with the proposed comment. 
Rather, the FAA is investigating this matter with ACG, EASA, and 
Diamond.
    Diamond is now planning a design and flight test review to 
determine the overall safety issues with regard to this recommendation, 
which could take a few months to complete.
    In the interim, the FAA has determined that the actions of this AD 
address the unsafe condition until further analysis is done. The FAA 
may consider further rulemaking action based on the evaluation. We are 
not changing the AD based on this comment.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD as proposed--except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Costs of Compliance

    We estimate that this AD affects 699 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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

    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),
