Main Landing Gear Doors - An Inspection and Modification of the Attachment Bolts of the Operating Rod Bracket to the Outer Skin and Modification of the Attachment Bolts to the Main Landing Gear (MLG) of the Carbon Fiber Reinforced Plastic (CFRP) MLG Outboard Doors

1. Planning Information

A. Effectivity

(1) F28 Mark 0070/0100 aircraft serial numbers: 11244 thru 11585

(2) Production version of this modification: Not applicable.

B. Concurrent Requirements

(1) For aircraft still equipped with CFRP MLG outboard doors, pn D13312-401 thru -410: Before, or at the same time as, you do this SB, you must do:

- SBF100-52-080 - DOORS – Main Landing Gear Doors – An Inspection and Modification of the Attachment of the Operating Rod Bracket to the Outer Skin of the Carbon Fiber Reinforced Plastic (CFRP) Main Landing Gear (MLG) Outboard Doors.

C. Reason

(1) An event occurred where, after landing gear down selection, a MLG unsafe indication appeared on the MFDU and the green MLG down and locked indication light remained off. Several cycles with the normal landing gear selector handle did not result in a down and locked situation for the MLG. Also after using the alternate procedure the problem persisted. When the aircraft finally landed the MLG involved was suddenly forced into its down and locked position. If equipped with CFRP MLG outboard doors.

This document has been supplied by Fokker Services B.V . to its customers on a confidential basis subject to the provisions of an agreement. Reproduction or disclosure to third parties of this document or any part thereof, or the use of any information contained there in for purposes other than explicitly allowed by the aforesaid agreement, is not permitted except with the prior written permission of Fokker Services B.V. However, due to this sudden movement a pressure pulse was generated as a result of which the other MLG got unlocked and collapsed.

(2) This SB only addresses the cause of the MLG not attaining its down and locked position in flight. Investigation revealed that the bracket of the rod in the MLG outboard door was detached from the outboard door, got stuck between the MLG and wing lower skin, thus obstructing the MLG to lock properly in flight.

(3) As a result of similar previous occurrences Service Bulletin SBF100-52-080 was already introduced, in December 2005, to in spect and modify the attachment of the operating rod bracket. After this modification several operators reported breaking of the recessed head of the titanium attachment bolts of the operating rod bracket to the CFRP MLG outboard door. The remaining bolt shafts are then pulled through the external repair patch and the carbon fiber door outer skin. The result could be that the operating rod, with the detached bracket, gets stuck between the MLG main fitting and wing lower skin. This could result in a MLG which will not come in the down and locked position during LG extension as reported (see also AOF100.166#03). The primary factor to the cause of breaking bolt heads has been determined to be the incorrect adjustment of the MLG outboard door.

(4) To prevent breaking of the recessed bolt heads of the operating rod bracket from the CFRP MLG outboard door and possible improper locking of the MLG, this Service Bulletin introduces:

- a detailed inspection for play or cracks in the recessed bolt heads in Part 1, and - a modification to improve the attachment of the operating rod bracket to the CFRP MLG outboard door and the introduction of a weaker (modified aluminum) bolt in the MLG attachment of the door operating rod, in Part 2.

(5) As an additional measure to prevent further economical damages MRB task 321201-00-03 has been introduced to inspect the CFRP MLG outboard door for play or cracks in the recessed countersunk heads of the operating rod bracket attachment bolts at a scheduled basis.

(6) For spare CFRP MLG outboard doors Component Service Bulletin (CSB) D13312-52-015 has been issued.

A. Inspect the CFRP MLG outboard door for play or cracks in the recessed bolt heads as follows:

(1) Remove the paint scheme from the bolt heads, if applicable.

(2) Apply a controlled load, by hand, to the outer end of the MLG outboard door (i.e. in an in- and outboard direction).

(3) At the same time inspect, on the outside of the door, whether there is free play between the countersunk bolt-heads and the external metal reinforcement plate and/or whether there are cracks in the bolt heads.

(4) If there is doubt about the countersunk bolt heads, remove the bolts one-by-one for a more detailed inspection and re-install them, when no cracks are found, in accordance with CMM chapter 52-82-05 and SRM chapter 51-45-01.
