### TITLE: LANDING GEAR - NOSE GEAR - INSPECTION OF NOSE LANDING GEAR MAIN FITTING AND SLIDING TUBE **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES In May of 2007 a crack was found on the main fitting of the Reinforced Nose Landing Gear (RNLG) leg during overhaul on an A340-313 aircraft. Following investigation, it has been concluded that the crack initiated as a result of residual stress in the part following impact damage. The impact damage was caused by a towing incident in January of 2001 when the RNLG leg was installed on another A340-313 aircraft. During aircraft pull forward the shear pin on the tow bar sheared and RNLG ran over the tow bar. A review of the records of past events revealed that a similar incident had occurred in September of 2004 on an A340-211 aircraft. During overhaul, a crack was found on the NLG sliding tube and this has been attributed to residual stress following an impact incident. A review of operator reported incidents has identified some Nose Landing Gear (NLG) Main Fittings and NLG Sliding Tubes on A330/A340 aircraft that have sustained impact as a result of towing incidents. This Service Bulletin is published to advise all operators of A340-200/300 aircraft of the issue of Messier-Dowty Service Bulletin No. D23581-32-061. This Inspection Service Bulletin (ISB) requires a one time Non-destructive Test (NDT) inspection (Magnetic Particle Inspection (MPI)) of the affected area(s) on (NLG) Main Fittings and NLG Sliding Tubes that have sustained impacts as a result of a towing incident to make sure that no cracks are present; within a grace period of 1,000 Flight Hours (FH) from the issue of Revision No. 01 of this Service Bulletin unless already performed via the SB revision 00.

# @A340 SERVICE BULLETIN SUMMARY This initial MPI looks for cracks in the area damaged during the impact, or if the exact location of damage cannot be confirmed, inspects the front 180 ̊ of the lower section of the main fitting and/or the front 120 ̊ of the lower section of the sliding tube. These are the main areas of the NLG most likely to be damaged during a towing incident. The inspection will require the removal of paint, surface protections and labels in the area to be inspected. If cracks are found the part must be replaced. If no cracks are found the area is to be flap peened to introduce surface compressive residual stress and corrosion protection, paint protection and labels arerestored. All inspection result (finding of damage including nil findings) must be reported to AIRBUS/MD. Following this initial MPI, repeat detailed inspections of the NLG Main Fittings and NLG Sliding Tubes are required every 900 FH for damage to the surface protections or corrosion in the affected area(s). If a visual inspection indicates damage to the paint or sealant around the labels or cadmium or base metal, then removal of paint, surface protections and labels is required followed by the MPI. Additionally, if any other area of the NLG that is not covered by this inspection has sustained impact damage as a result of a towing incident and the part has not been removed from service, operators are advised to contact Airbus/MBD. The inspection is normally to be carried out "weight-on-wheels". NOTE: It will only be necessary to remove the wheels and towing fitting if the location of impact damage is unknown or if impact damage is located in the area of the towing fitting. Accomplishment of this ISB will provide early detection of cracks in the area(s) of the NLG Main Fittings and NLG Sliding Tubes that have sustained impacts as a result of towing incident and make sure of continued airworthiness of these NLG Main Fittings and NLG Sliding Tubes.
