AD NUMBER: 2008-12-19
SUBJECT: Airworthiness Directive 2008-12-19 SUMMARY: We are adopting a
new airworthiness directive (AD) for the products listed above.
This 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 MCAI describes the unsafe condition as: This Airworthiness
Directive (AD) is issued following the discovery of a potential
chafing between the feeder bundle and the right side partition wall
separating the cabin from the lavatory at frames 22/23. This
chafing may damage the feeder bundle and cause a sustained
smoke-generating short-circuit between the feeder and the partition
wall made of resistive composite material. Strong smoke and a
difficult-to-localize short-circuit may result in a hazardous
situation. The unsafe condition is sustained smoke in the cabin,
which may lead to reduced ability of the flight crew to operate the
airplane. We are issuing this AD to require actions to correct the
unsafe condition on these products.
