WINGS SLATS SLAT TRACKS #6 #7 #8 - "EXTENSION" MECHANICAL STOP INSPECTION

1. PLANNING INFORMATION A. EFFECTIVITY This Service Bulletin is applicable to:

• F2000EX aircraft with serial numbers 10, 12, 13, 47, 56, 67, 81, 88, 92, 104, 116, 135, 136, 161, 184, 197, 213, 259, 263 through 296 (F2000EX, F2000EX EASy, F2000LX and F2000LXS),

• F2000EX aircraft with serial number 602 (F2000DX),

• F2000EX aircraft with serial numbers 706 through 730 (F2000S).

B. REASON On some aircraft in-service, the screw of the slat mechanical stop assembly on slat tracks #6, #7 and #8 was found loose.

This situation caused some structural damage to the wing front spar and, in a few cases, a puncture in the fuel cap, leading to fuel leakage. An improper installation of the lockwashers on the screws is suspected.

The purpose of this Service Bulletin is to verify the proper installation of the screws and to re-install them if necessary.

C. DESCRIPTION This Service Bulletin consists in:

• Verifying the tightening of the screw and the proper lockwasher installation at the slat tracks #6, #7 and #8.

• Replacing and re-installing the screw lockwashers, if needed.

D. COMPLIANCE If you choose to comply with this Service Bulletin, accomplishment is to be performed during the next “9M or 440FH” inspection.

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

F. LABOR Estimated labor-hours: Refer to Service Bulletin Commercial Summary.

NOTE: These labor-hours only concern the work described in this Service Bulletin and do not include other maintenance work that may be performed on this occasion.

G. MATERIAL - PRICE AND AVAILABILITY The modification kit may be obtained from either address listed below:
