MODIFICATIONS
MODIFICATION CLASSIFICATION MAJOR 207165H16972 MINOR None NOTE : As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes.
REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES There has been an in service occurrences of damage being found on the bogie pivot pin. The probable root cause of this damage is due to operation on runways that increase the pressure-velocity in the joint leading to the production of a higher than acceptable energy input into the bogie pivot joint which results in heat damage to the bogie pivot pin.
The aim of this Service Bulletin is to improve the robustness of the bogie pivot pin in high pressurevelocity environments. Specifically when oscillations close to the natural frequency of the bogie beam assembly are encountered.
This Service Bulletin introduces:
- A bogie pivot pin fabricated from CRES custom 465 H950 with chrome plating
- Sliding tube and bogie beam bushes fabricated from copper alloy (ToughMet 3) material with ladder-grooves
- Bogie pivot pin nut and locking ring fabricated from CRES 13-8 Mo H1000 with chrome plating
- Bolts and washers fabricated from CRES A286
- MIL-PRF-23827 Type 1 grease.
This Service Bulletin is published to advise all operators of A340 aircraft of the issue of SAFRAN LANDING SYSTEMS UK Ltd Service Bu lletin No. A33/34-32-315 which r eplaces the bogie pivot pin.
