Models named: ATR42-200, -300, -320, -500. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to ATR-GIE Avions de Transport Régional Model ATR42-200, -300, -320, and -500 airplanes; and ATR72-101, -201, -102, -202, -211, -212, and -212A airplanes; certificated in any category; all certified models; all manufacturer serial numbers.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
This paragraph restates the requirements of paragraph (g) of AD 2015-23-12, with terminating action. For Model ATR72 airplanes: Within 12 months after December 29, 2015 (the effective date of AD 2015-23-12), inspect for the serial number of the left-hand (LH) and right-hand (RH) MLG rear hinge pins having part number (P/N) D61000. A review of airplane maintenance records is acceptable in lieu of this identification if the part number and serial number of the LH and RH MLG rear hinge pins can be conclusively determined from that review. If a rear hinge pin having P/N D61000 has a serial number listed in Messier-Bugatti-Dowty Service Bulletin 631-32-213, dated December 16, 2013; or Messier-Bugatti-Dowty Service Bulletin 631-32-216, Revision 1, dated December 17, 2013; as applicable: Within 12 months after December 29, 2015, replace the pin with a serviceable part as identified in paragraph (h) of this AD, in accordance with the Accomplishment Instructions of Messier-Bugatti-Dowty Service Bulletin 631-32-213, dated December 16, 2013; or Messier-Bugatti-Dowty Service Bulletin 631-32-216, Revision 1, dated December 17, 2013; as applicable. Accomplishment of the actions required by paragraph (l) of this AD terminates the inspection required by this paragraph. Accomplishing the actions required by paragraph (m) or (o) of this AD terminates the actions required by this paragraph.
Unsafe condition
This AD was prompted by a new occurrence of a cracked main landing gear (MLG) rear hinge pin. We are issuing this AD to detect and correct cracked rear hinge pins, which could lead to MLG structural failure, possibly resulting in collapse of the MLG and consequent injury to the occupants of the airplane.
Affected ADs
This AD replaces AD 2015-23-12, Amendment 39-18329 (80 FR 73096, November 24, 2015) (“AD 2015-23-12”).
