Within 180 hours TIS after the effective date of this AD, remove the rotary buckle sub-assembly and replace it with a part eligible for installation. (ii) If the straps release from the restraint system, within 180 hours TIS after the effective date of this AD, remove the rotary buckle sub-assembly and replace it with a part eligible for installation. (2) For restraint systems, P/N 358XX-XXX-YY-ZZZ (where 358XX-XXX-YY-ZZZ can be any combination of numbers and/or letters), having S/Ns 738-1619 (inclusive), within 30 hours TIS after the effective date of this AD, inspect the restraint system for proper release of the straps from the restraint system. (i) If the straps do not release from the restraint system, before further flight, placard the seat as inoperative and within 180 hours TIS after the effective date of this AD, remove the restraint system from service and replace it with a part eligible for installation. (ii) If the straps release from the restraint system, within 180 hours TIS or six months after the effective date of this AD, whichever occurs first, remove the restraint system from service and replace it with a part eligible for installation.
Unsafe condition
This AD was prompted by reports to the European Union Aviation Safety Agency (EASA), since the publication of AD 2017-16-04, of additional restraint system buckle knobs breaking on a batch of parts outside of the population identified in AD 2017-16-04. The FAA is issuing this AD to prevent a restraint system strap from failing to release from the buckle, causing occupants to be unable to exit the aircraft during an emergency. The unsafe condition, if not addressed, could result in a restraint system strap failing to release from the buckle, resulting in injury or death of the occupant.
Affected ADs
This AD replaces AD 2017-16-04, Amendment 39-18981 (82 FR 39355, August 18, 2017).
