PILOT AND COPILOT SEAT INSTALLATION IMPROVEMENT

1. PLANNING INFORMATION

A. EFFECTIVITY

This Service bulletin is applicable to FALCON 900 aircraft with serial numbers 1 through 202 which have

already performed their first "C" inspection and which are equipped with pilot seats P/N 132series.

B. REASON

A Falcon operator reported that during take-off at rotation phase, the copilot seat slid aft.

Investigations showed that one locking spring fitted on a seat locking pin was broken and the other one

weak.

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"

inspection.

NOTE: The replacement of these springs and the check of the correct locking of the seats will be added

in to next revision of the scheduled maintenance program, every "C" inspection.

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.

E. APPROVAL

The technical content of this document is approved under the authority of DOA nr. EASA.21J.051.

F. LABOR

NOTE: These labor-hours only concern the work described in this Service Bulletin and do not include
