AGENC¥: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM)_

SUMMARY: We propose to adopt a new ainvorthiness directive (AD) for the products

listed above. This proposed AD results from mandatory continuing airworthiness

information (MCAI) originated by an aviation authority of another country to identify

and correct an unsafe condition on an aviation product. The MeAl describes the Wlsafe

condition as:

Cracks have been found on scats backrest links PIN (part nwnber)

90-000200-104-1 and 90-000200-104-2. These cracks can significantly

affect the structural integrity of seat backrests.

Failure of the backrest links could result in injury to an occupant during emergency

conditions. The proposed AD would require actions that are intended to address the

unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by [insert date 30 days after

date of publication in the FEDERAL REGISTER].
