14 CFR Part 39

[Docket No. FAA-2012-1251; Directorate Identifier 2012-CE-044-AD]
RIN 2120-AA64

Airworthiness Directives; Pacific Aerospace Limited Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Pacific Aerospace Limited Models FU24-954 and FU24A-954 airplanes that 
would supersede an existing AD. This proposed AD results from mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as aircraft operating outside the aircraft aft center of 
gravity (C of G) limits during parachute-drop operations. Exceeding C 
of G limits could result in loss of control of the aircraft. We are 
issuing this proposed AD to require actions to address the unsafe 
condition on these products.

DATES: We must receive comments on this proposed AD by January 14, 
2013.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.
     Fax: (202) 493-2251.

Discussion

    On September 21, 2010, we issued AD 2010-20-18, Amendment 39-16453 
(75 FR 59606, September 28, 2010). That AD required actions intended to 
address an unsafe condition on the products listed above.
    Since we issued AD 2010-20-18, Amendment 39-16453 (75 FR 59606, 
September 28, 2010), information has been received that shows that the 
operating limitations required by this AD should be different between 
turbine engine and piston engine Pacific Aerospace Limited Models FU24-
954 and FU24A-954 airplanes.
    The Civil Aviation Authority (CAA), which is the aviation authority 
for New Zealand, has issued AD DCA/FU24/182, dated October 25, 2012 
(referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The new MCAI AD supersedes the 
requirements in AD DCA/FU24/179.
    The new MCAI requires adding a requirement to install station 
marking placards inside the rear cabin walls and inserting a supplement 
into the airplane flight manual (AFM) specifically approved for 
parachuting operations that contains detailed information for 
determining the weight and balance of the aircraft for turbine engine 
airplanes. This proposed AD also retains all actions in AD 2010-20-18, 
Amendment 39-16453 (75 FR 59606, September 28, 2010), for all 
airplanes.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Costs of Compliance

    We estimate that this proposed AD would affect 1 product of U.S. 
registry. We also estimate that it would take about 22 work-hours per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $1,870 per product.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue

[[Page 71358]]

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    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]

    2. The FAA amends Sec.  39.13 by removing AD 2010-20-18, Amendment 
39-16453 (75 FR 59606, September 28, 2010), and adding the following 
new AD:

Pacific Aerospace Limited: Docket No. FAA-2012-1251; Directorate 
Identifier 2012-CE-044-AD.

(a) Comments Due Date

    We must receive comments by January 14, 2013.

(b) Affected ADs

    This AD supersedes AD 2010-20-18, Amendment 39-16453 (75 FR 
59606, September 28, 2010).

(c) Applicability

    This AD applies to Pacific Aerospace Limited Models FU24-954 and 
FU24A-954 airplanes, all serial numbers, that are:
    (1) certificated in any category; and
    (2) modified to conduct parachute operations.

(d) Subject

    Air Transport Association of America (ATA) Code 8: Leveling and 
Weighing.

(e) Reason

    This AD was prompted by reports of aircraft operating outside 
the aft center of gravity (C of G) limits during parachute-drop 
operations. We are issuing this AD to prevent exceeding C of G 
limits, which could result in loss of control of the aircraft.

(f) Actions and Compliance for All Airplanes (Both Turbine and Piston 
Engine Airplanes) Retained From AD 2010-20-18, Amendment 39-16453 (75 
FR 59606, September 28, 2010)

    Unless already done, do the following actions:
    (1) As of October 18, 2010 (the effective date retained from AD 
2010-20-18, Amendment 39-16453 (75 FR 59606, September 28, 2010)), 
before further parachute-drop operations:
    (i) Amend the airplane flight manual (AFM) to restrict maximum 
occupancy of the cabin aft of fuselage station (F.S) 118.84 to 6 
persons. This may be done by inserting a copy of this AD into the 
AFM adjacent to the applicable supplement for parachuting 
operations; and
    (ii) Fabricate a placard at least 2 by 4 inches (using at least 
\1/8\-inch letters) and install the placard in two places, one on 
each side of the aft cabin, in view of all occupants as they enter 
and occupy the cabin which states the following: Maximum occupancy 
of this cabin limited to six persons for parachuting operations. 
Weight and Balance must be confirmed for each flight.
    (2) As of October 18, 2010 (the effective date retained from AD 
2010-20-18, Amendment 39-16453 (75 FR 59606, September 28, 2010)), 
before further parachute-drop operations, the weight and balance 
calculation must comply with the following limitations and establish 
that the aircraft C of G will remain within AFM limits for the 
duration of the flight:
    (i) Use actual weights for all occupants and their equipment to 
do the calculation;
    (ii) Account for the positions of all occupants in the 
calculation. Do the calculation with the occupants' (parachuting 
group) positions at the most aft positions that result from the 
rearmost members of the group sitting against the aft cabin wall and 
subsequent occupants located immediately forward of them, unless a 
means of restraint is provided to prevent the occupants moving 
rearwards from their normal position; and (iii) Keep a record of the 
C of G determination for each parachuting operation.

(g) New Actions and Compliance for Turbine Engine Airplanes

    Within the next 15 days after the effective date of this AD, do 
the following:
    (1) Add fuselage station (F.S.) reference line placards inside 
the rear cabin walls following the instructions in Section 2.5, 
Placards, of the CAA Approved AFM Supplement for Aircraft Modified 
for Parachuting Operations, PT6 Fletcher-EX Document Reference: AIR 
2817-FMS-P1, dated October 15, 2012, or Walter Fletcher Document 
Reference: AIR 2672-FMS-P1, dated October 15, 2012, as applicable.
    (2) Insert Section 2.4, Weight and Balance, of the CAA Approved 
AFM Supplement for Aircraft Modified for Parachuting Operations, PT6 
Fletcher-EX Document Reference: AIR 2817-FMS-P1, dated October 15, 
2012, or Walter Fletcher Document Reference: AIR 2672-FMS-P1, dated 
October 15, 2012, as applicable, into the AFM.

(h) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Standards Office, FAA, has the authority to approve AMOCs for this 
AD, if requested using the procedures found in 14 CFR 39.19. Send
