## 2. Planning Information

A. Effectivity

(1) F28 Mark 0070/0100 aircraft serial numbers: 11258, 11272 thru 11286, 11290, 11291, 11293, 11295, 11296, 11300, 11303, 11306 thru 11308, 11310 thru 11316, 11318 and 11320 thru 11585.

NOTE: Aircraft serial numbers 11471 and 11502 have been repaired in accordance with the instructions of CAS-38062, respectively CAS-41986, and can be identified in the aircraft records as to comply with the repair requirements of this Service Bulletin (SBF100-53-129).

B. Concurrent Requirements

(1) Not applicable.

C. Reason

(1) Service experience has shown that cracking can occur in the pressure bulkhead webplate and skin connection angle on the RH side at station 14911 (station 12447 for F28 Mark 0070), stringer 67 of aircraft fuselage section 2 before the existing threshold per ALS task 533016-00-03 (F28 Mark 0100) or 533016-01-03 (F28 Mark 0070). Therefore an additional one-time inspection has been introduced with SBF100-53-128. If cracks have occurred on the pressure bulkhead webplate and/or skin connection angle these can be repaired in accordance with this Service Bulletin (SBF100-53-129).

D. Description

(1) This Service Bulletin tells you how to:

- Gain access to the aft side, forward side and outside of the pressure bulkhead webplate and skin connection angle - Remove the necessary parts - Repair the found cracks - Reinstall the removed parts - Close up the work area.
