The purpose of this Service Bulletin is to replace the locking springs on both pilot and copilot seats and

then, check the correct locking of the seats on all aircraft which have already performed their first "C"

C. DESCRIPTION

The operation consists in:

• replacing the locking pin springs of each seat,

• verifiying the correct locking of the seat after improvement.

D. COMPLIANCE

If you choose to comply with this Service Bulletin, accomplishment should be performed at the first

opportunity but no later than the next "A" inspection.
