MODIFICATIONS
MODIFICATION CLASSIFICATION MAJOR 207649H17111 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 The bogie pivot pin links the MLG sliding tube to the bogie beam. This component is a principal structural element.
There have been a number of in-service occurrences of damage being found in the form of chrome detachment or cracking to the bogie pivot pin. In some cases the base metal has also displayed corrosion and cracking. The root cause of the damage is due to operation on runways that increase the pressure in the bogie pivot joint, leading to higher than acceptable energy production resulting in heat damage.
The aim of this Service Bulletin is to improve the robustness of the bogie pivot pin in high pressure velocity environments. This Service Bulletin is published to advise operators of A340 aircraft of the issue of SAFRAN LANDING SYSTEMS UK Ltd Servic e Bulletin No. A33/34- 32-319 and A33/34-32-320.
SAFRAN LANDING SYSTEMS UK Ltd Service Bulletin No. A33/34-32-319 and A33/34-32-320 details:
- 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 collar fabricated from CRES 13-8 Mo H1000 with chrome plating

There have been a number of in-service occurrences of damage being found in the form of chrome detachment or cracking to the bogie pivot pin. In some cases the base metal has also displayed corrosion and cracking. The root cause of the damage is due to operation on runways that increase the pressure in the bogie pivot joint, leading to higher than acceptable energy production resulting in heat damage.
(2) Objective/Action The aim of this Service Bulletin is to improve the robustness of the bogie pivot pin in high pressure velocity environments. This Service Bulletin is published to advise operators of A340 aircraft of the issue o f SAFRAN LANDING SYSTEMS UK Ltd Service Bulletin No. A33/34-32-319 and A33/34-32-320.
SAFRAN LANDING SYSTEMS UK Ltd Service Bulletin No. A33/34-32-319 and A33/34-32-320 details:
