Airworthiness Directive · Amendment 39-18883 · Nacelles/pylons
Textron Aviation Inc. Airplanes
This AD applies to Textron Aviation Inc. (type certificate previously held by Cessna Aircraft Company) Model 402C airplanes, serial numbers 402C0001 through 402C1020, and Model 414A airplanes, serial numbers 414A0001 through 414A1212, that are certificated in any category; and are equipped with either of the following:
(1) Cessna Multi-Engine Service Kit SK402-47, “Lower Front Wing Spar Cap Inspection/Modification,” Original Issue, Revision A, or Revision B; or
(2) Nacelle fittings part numbers (P/Ns) 5292029-9, 5292029-10, 5292029-11, 5292029-12, 5292029-21, 5292029-22, 5292029-23, or 5292029-24.
Note 1 to paragraph (c) of this AD: P/Ns 5292029-9, 5292029-10, 5292029-11, 5292029-12, 5292029-21, 5292029-22, 5292029-23, or 5292029-24 were installed when the Cessna Multi-Engine Service Kit SK402-47 was installed.
We are adopting a new airworthiness directive (AD) for certain Textron Aviation Inc. Models 402C and 414A airplanes (type certificate previously held by Cessna Aircraft Company). This AD requires inspecting the nacelle fittings for cracks, replacing if necessary, and reporting the results of the inspection to the FAA. This AD was prompted by reports of cracks found on certain nacelle fittings. We are issuing this AD to correct the unsafe condition on these products.
Inspect the nacelle fitting following the Accomplishment Instructions (except for paragraph 6) in Textron Aviation Mandatory Multi-engine Service Letter MEL-54-02, Revision 2, dated March 29, 2017, at the applicable compliance times specified in paragraphs (g)(1) through (2) of this AD.
(1) For airplanes with less than 7,400 hours time-in-service (TIS) on the affected nacelle fitting: Before or upon accumulating 3,500 hours (TIS) on the nacelle fitting or within the next 100 hours TIS after June 7, 2017 (the effective date of this AD), whichever occurs later. Repetitively thereafter inspect every 120 hours TIS until the nacelle fitting has reached 7,500 hours TIS. When the airplane reaches 7,500 hours TIS on the affected nacelle fitting, the repetitive inspection time must be changed to 60 hours TIS. A 10-hour TIS grace period is allowed for those airplanes between 51 and 110 hours TIS for the first repetitive inspection when the airplane reaches 7,500 hours TIS on the nacelle.
(2) For airplanes with 7,400 hours TIS or more on the affected nacelle fitting: Before or upon accumulating 7,500 hours TIS on the nacelle fitting or within the next 25 hours TIS after June 7, 2017 (the effective date of this AD), whichever occurs later. Repetitively thereafter inspect every 60 hours TIS.
(1) If cracks are found during any inspection required in paragraph (g) of this AD, before further flight, replace the cracked nacelle fitting.
(2) If a cracked nacelle fitting P/N 5292029-9, 5292029-10, 5292029-11, 5292029-12, 5292029-21, 5292029-22, 5292029-23, or 5292029-24, is replaced with a new nacelle fitting P/N 5292029-9, 5292029-10, 5292029-11, 5292029-12, 5292029-21, 5292029-22, 5292029-23, or 5292029-24, the new part is subject to the requirements of this AD.
Within 10 days after doing the initial inspection in paragraph (g) of this AD or within 10 days after June 7, 2017 (the effective date of this AD), whichever occurs later, using the Attachment to Textron Aviation Mandatory Multi-engine Service Letter MEL-54-02, Revision 2, dated March 29, 2017, “Visual Inspection Results Form,” complete the report and send a copy to the Wichita Aircraft Certification Office (ACO) at the address listed in paragraph (m) of this AD or by email to Wichita-COS@faa.gov.
This AD allows credit for the inspections required in paragraph (g) of this AD if done before June 7, 2017 (the effective date of this AD), following Textron Aviation Mandatory Multi-engine Service Letter MEL-54-02, dated December 23, 2016, or Textron Aviation Mandatory Multi-engine Service Letter MEL-54-02, Revision 1, dated March 22, 2017.
