Airworthiness Directives; The Boeing Company Model 757-200 Series 
Airplanes Modified by Supplemental Type Certificate (STC) ST01529SE or 
STC ST02278SE

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 757-200 series airplanes modified by 
particular STCs. This AD was prompted by reports of a main cargo door 
being blown past its full open position while on the ground during 
gusty wind conditions, which resulted in uncontrolled fall down to its 
closed position. This AD requires installing a new placard and bracket, 
replacing an existing placard, and replacing the main cargo door 
control panel. We are issuing this AD to prevent damage to the main 
cargo door, which could result in rapid decompression of the airplane, 
or injury to maintenance and ground crew during ground operations.

DATES: This AD is effective April 4, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 4, 
2016.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain The Boeing Company 
Model 757-200 series airplanes modified by particular STCs. The NPRM 
published in the Federal Register on June 5, 2015 (80 FR 32061) (``the 
NPRM''). The NPRM was prompted by reports of a main cargo door being 
blown past its full open position while on the ground during gusty wind 
conditions, which resulted in uncontrolled fall down to its closed 
position. The NPRM proposed to require installation of a new placard 
and bracket, replacement of an existing placard, and replacement of the 
main cargo door control panel. We are issuing this AD to prevent damage 
to the main cargo door, which could result in rapid decompression of 
the airplane, or injury to maintenance and ground crew during ground 
operations.

Comments

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

Request To Revise Description of the Unsafe Condition

    Precision Conversions, LLC requested that we revise the SUMMARY and 
Discussion sections of the NPRM and the unsafe condition section of the 
proposed AD. Precision Conversions, LLC stated that it was concerned by 
certain conclusions stated in the NPRM for which it does not believe 
there is a factual basis. Precision Conversions, LLC noted that the 
NPRM stated that wind damage to a cargo door could result in rapid 
decompression, leading to in-flight breakup. However, even without the 
accomplishment of Precision Conversions Service Bulletin PC-757-11-
0023, dated August 1, 2014, Precision Conversions, LLC stated that the 
suggested scenario would not occur. If, during ground operations, the 
main cargo door were to deflect beyond the fully open position enough 
to be of concern, its damaged operating system would prevent the cargo 
door from closing as usual, which would not go unnoticed by the crew, 
and the airplane would not be dispatched. Thus, a potential unsafe 
condition would occur only on the ground, not in the air.
    Precision Conversions, LLC stated that a potential for an unsafe 
condition does arise from the possibility of ground crew operating the 
main cargo door outside of the wind limits published in the aircraft 
maintenance manual and operations manual supplements. Precision 
Conversions, LLC asserted that exceeding published limits could result 
in damage to the door operating system and loss of control of the door, 
creating an unsafe condition, but only during ground operations; thus, 
Precision Conversions, LLC believed that the proposed language 
regarding rapid decompression and in-flight breakup had no basis, given 
the relevant factual scenario, and should not be included in the final 
rule. Precision Conversions, LLC requested that we revise the unsafe 
condition to indicate that the NPRM will ``prevent wind damage to the 
main cargo door operating system and ensure its safe use during ground 
operations.''
    We partially agree with the request. We disagree that a damaged 
door will always be detected because of human factors. We agree, 
however, that rapid decompression might not necessarily lead to in-
flight breakup, which would depend on the decompression. We have 
therefore revised the SUMMARY and Discussion sections of this final 
rule and paragraph (e), Unsafe Condition, of this AD to remove 
reference to in-flight breakup, and to include injury to maintenance 
and ground crew during ground operations.

Statement Regarding Content of NPRM

    Boeing stated that the NPRM does not address or affect any Boeing 
designs; therefore, Boeing can neither review the data nor comment on 
the content of the NPRM.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed Precision Conversions LLC Service Bulletin PC-757-11-
0023, dated August 1, 2014. The service information describes 
procedures for installing a new placard and bracket, replacement of an 
existing placard, and replacement of the main cargo door control panel. 
This service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 9 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

[[Page 10074]]

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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.
