Airworthiness Directives; M7 Aerospace LLC Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
M7 Aerospace LLC Models SA26-AT, SA226-T, SA226-AT, SA226-T(B), SA226-
TC, SA227-AT, SA227-TT, SA227-AC (C-26A), SA227-BC (C-26A), SA227-CC, 
and SA227-DC (C-26B) airplanes. This proposed AD was prompted by 
information that the airplane flight manual (AFM) does not provide 
adequate guidance in the handling of engine failures, which may lead to 
reliance on the negative torque system (NTS) for reducing drag. This 
condition could lead the pilot to not fully feather the propeller with 
consequent loss of control. This proposed AD would require inserting 
updates into the airplane flight manual (AFM) and/or the pilot 
operating handbook (POH) that will clearly establish that the NTS is 
not designed to automatically feather the propeller but only to provide 
drag protection. We are proposing this AD to correct the unsafe 
condition on these products.

DATES: We must receive comments on this proposed AD by October 9, 2015.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The FAA received a report of an accident where an M7 Aerospace LLC 
Model SA227-AC airplane experienced left engine power loss and 
consequent loss of control. Training manuals provide descriptions of 
the negative torque system (NTS), which provides partial anti-drag 
protection if a negative torque condition is sensed. This feature might 
cause pilots to assume the system automatically provides full anti-drag 
protection in the event of an engine failure or power loss. The pilot 
must also take prompt action to fully feather the propeller on the 
failed engine to reduce drag. A pilot's sole reliance on the NTS for 
reducing drag in the event of engine power loss may result in the 
pilot's failure to initiate the Engine Failure Inflight checklist and 
feather the propellers in time.
    This condition, if not corrected, could result in loss of control 
of the aircraft due to excessive asymmetric drag.

    The M7 Aerospace LP service information describes procedures for 
inflight engine shutdown procedures. 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 of this NPRM.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.
    In addition, minimum controllable airspeed for single engine 
landing is being investigated for possible future action.

Proposed AD Requirements

    This proposed AD would require updates be inserted into the AFM 
that will clearly establish that the NTS is not designed to 
automatically feather the propeller but only to provide drag 
protection.
    The proposed requirements do not address anything on the above-
referenced minimum controllable airspeed for single engine landing.

Costs of Compliance

    We estimate that this proposed AD affects 360 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed 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

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD 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.
    For the reasons discussed above, I certify this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the 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.

(a) Comments Due Date

    We must receive comments by October 9, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to M7 Aerospace LLC Models SA26-AT, SA226-T, 
SA226-AT, SA226-T(B), SA226-TC, SA227-AT, SA227-TT, SA227-AC (C-

all serial numbers, certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 01, Operations

(e) Unsafe Condition

    This AD was prompted by information that a pilot's sole reliance 
on the NTS for reducing drag in the event of engine power loss may 
result in the pilot's failure to initiate the Engine Failure 
Inflight checklist and feather the propellers in time. This could 
lead the pilot to not fully feather the propeller with consequent 
loss of control. We are issuing this AD to add information to the 
AFM and/or POH that reliance on the NTS to reduce drag during an 
engine failure could lead the pilot to not fully feather the 
propeller with consequent loss of control.

    Comply with this AD within 30 days after the effective date of 
this AD, unless already done.
