Ipeco Pilot and Co-Pilot Seats
Superseded. A later AD replaced this one: AD 2023-14-10. Comply with the one in force.
(1) This AD applies to:
(i) Ipeco Holdings Limited (Ipeco) pilot and co-pilot seats with a part number (P/N) listed in Paragraph 1.A., Planning Information, Tables 1 and 2, of Ipeco Service Bulletin (SB) Number 063-25-14, Revision 00, dated August 14, 2018, and
(ii) Ipeco pilot seat P/N 3A063-0099-01-1 and Ipeco co-pilot seat P/N 3A063-0100-01-1.
(2) These seats are installed on, but not limited to, ATR-GIE Avions de Transport Regional ATR 42 and ATR 72 airplanes.
The FAA is superseding Airworthiness Directive (AD) 2017-22-02 for certain Ipeco Holdings Limited (Ipeco) pilot and co-pilot seats. AD 2017-22-02 required modification and re-identification of the affected seats. This AD continues to require modification and re-identification of the affected seats. This AD also requires initial and repetitive inspections of the affected tracklock springs and, depending on the findings, replacement of the tracklock springs with a part eligible for installation. This AD was prompted by reports that the tracklock spring modification required by AD 2017-22-02 does not adequately address the issue of unexpected seat movement during takeoff and landing and the need to add additional seat part numbers (P/Ns) to the applicability. The FAA is issuing this AD to address the unsafe condition on these products.
(1) For seats that have not installed the tracklock spring modification kit, within two years after December 12, 2017 (the effective date of AD 2017-22-02), modify and re-identify each affected pilot and co-pilot seat. Use the Accomplishment Instructions of Ipeco SB Number 063-25-08, Revision 00; Ipeco SB Number 063-25-09, Revision 00; or Ipeco SB Number 063-25-10, Revision 00; all dated May 31, 2016, as appropriate, to do the modification and re-identification.
(2) For all affected seats:
(i) Within 750 flight hours (FHs) after the effective date of this AD, and, thereafter at intervals not to exceed 750 FHs, inspect the tracklock spring of each seat in accordance with the Accomplishment Instructions, paragraph 3.2, of the Ipeco SB Number 063-25-14, Revision 00, dated August 14, 2018.
(ii) If, during any inspection as required by paragraph (g)(2)(i) of this AD, any damage on, or incorrect installation of, any tracklock spring is found on the pilot or co-pilot seat, before further flight, replace both tracklock springs of the affected seat with a part eligible for installation using the Accomplishment Instructions, paragraphs 3.3.3.1 or 3.3.3.2, as applicable, of the Ipeco SB Number 063-25-14, Revision 00, dated August 14, 2018.
(3) Within 30 days after the initial and repetitive inspections, and thereafter for two years after the effective date of this AD, send the inspection results, including no findings, to Ipeco at technicalsupport@ipeco.com.
After the effective date of this AD, do not install any pilot or co-pilot seat identified in paragraph (c)(1)(i) of this AD unless the seat is modified and re-identified as specified in paragraph (g)(1) of this AD.
(1) For the purpose of this AD, “damage” includes cracks, breaks, corrosion, or deformation of the tracklock spring.
(2) For the purpose of this AD, “incorrect installation” is installing the tracklock spring at an angle or position different from the angle or postion shown in Figures 6 and 7 of Ipeco SB Number 063-25-14, Revision 00, dated August 14, 2018.
(3) For the purpose of this AD, a “part eligible for installation” is:
(i) A modified seat provided, before installation, it has passed an inspection (no damage or defect found); and
(ii) a tracklock spring provided that it passed an inspection (no damage or defect found).
