Airworthiness Directives; Fokker Services B.V. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. 
This proposed AD was prompted by a report that the retraction actuator 
eye-end of a Goodrich main landing gear (MLG) failed. This proposed AD 
would require a one-time general visual inspection of the left-hand 
(LH) and right-hand (RH) MLG retraction actuators and replacement if 
necessary. We are proposing this AD to address the unsafe condition on 
these products.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0001, dated January 4, 2018 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for Fokker Services B.V. Model F28 Mark 
0070 and 0100 airplanes. The MCAI states:

    An occurrence was reported where, following take-off after gear 
up selection, the retraction actuator eye-end (P/N [part number] 
41518-3) of a Goodrich MLG failed. After the LG UNSAFE indication, 
the flight crew successfully selected gear down and locked by 
applying the alternate extension procedure, and an uneventful 
landing was made. Investigation results showed that the final 
overload fracture of the eye-end was preceded by fatigue cracks, 
believed to have been caused by interference between the MLG 
retraction actuator eye-end and the actuator bracket. It was also 
highlighted that the affected eye-end had been installed 
incorrectly, i.e. with the grease nipple located on the lower side, 
thus causing damage to the eye-end due to interference with the 
bracket. Further investigations revealed other occurrences of 
interference between retraction actuator eye-end and bracket with 
resulting damage.
    This condition, if not detected and corrected, could prevent 
retraction of the MLG and/or its complete extension, possibly 
resulting in damage to the aeroplane during landing, and consequent 
injury to occupants.
    To address this potential unsafe condition, Fokker Services 
published SBF100-32-168 to provide inspection and replacement 
instructions.
    For the reasons described above, this AD requires a one-time 
[general visual] inspection [for deficiencies] (check the eye-end 
for presence of interference/damage and for orientation of the 
greasing nipple) of the MLG retraction actuators, left-hand (LH) and 
right-hand (RH) sides, and, depending on findings, replacement.

    You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0303.

Related Service Information Under 1 CFR Part 51

    Fokker Services B.V. has issued Fokker Service Bulletin SBF100-32-
168, dated May 22, 2017. This service information describes procedures 
for a one-time general visual inspection for deficiencies of the 
Goodrich MLG retraction actuators and replacement of the actuator if 
necessary (e.g., if the retraction actuator greasing nipple is not 
located on the upper side MLG retraction actuator eye-end or if 
interference damage or evidence of removed damage is present on the 
eye-end of the MLG retraction actuator). 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.

FAA's Determination and Requirements of This 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 the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an 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 affects 5 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                Cost on U.S.
            Action                   Labor cost         Parts cost      Cost per product          operators
----------------------------------------------------------------------------------------------------------------
Inspection....................  1 work-hour x $85                 $0  $85 per inspection    $425 per inspection
                                 per hour = $85 per                    cycle.                cycle.
                                 inspection cycle.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of aircraft that might need 
these replacements:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------

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.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to transport category airplanes to the Director of the System Oversight 
Division.

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:

(a) Comments Due Date

    We must receive comments by June 11, 2018.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Fokker Services B.V. Model F28 Mark 0070 and 
0100 airplanes, certificated in any category, all serial numbers, if 
equipped with Goodrich main landing gear (MLG), part number (P/N) 
41050-x (all dashes) or P/N 41060-x (all dashes).

(d) Subject

    Air Transport Association (ATA) of America Code 32, Landing 
gear.

(e) Reason

    This AD was prompted by a report that the retraction actuator 
eye-end of a Goodrich MLG failed. We are issuing this AD to address 
failure of the retraction actuator eye-end of a Goodrich MLG, which 
could prevent retraction of the MLG and/or its complete extension, 
possibly resulting in damage to the airplane during landing, and 
consequent injury to occupants.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Definition

    For the purposes of this AD, a ``serviceable part'' is a 
serviceable retraction actuator with an eye-end that does not have 
any indication of interference or damage, as specified in the 
Accomplishment Instructions of Fokker Service Bulletin SBF100-32-
168, dated May 22, 2017.

(h) Inspection and Corrective Action

    Within 12 months after the effective date of this AD, perform a 
general visual inspection of the left-hand (LH) and right-hand (RH) 
MLG retraction actuators for deficiencies (i.e., check for the 
presence of interference damage, including evidence of removed 
damage, and for the orientation of the greasing nipple). If any 
deficiency is found, before further flight, replace the affected MLG 
retraction actuator with a serviceable part in accordance with the 
Accomplishment Instructions of Fokker Service Bulletin SBF100-32-
168, dated May 22, 2017.

(i) Other FAA AD Provisions
