Sliding Door Labels ASB No. AS350-52.00.53
Summary: Airbus Helicopters was informed that the LH rear support that attaches the rear intermediate roller of the sliding door was found cracked. After investigation, it was confirmed that pushing on the rear part of the rear support was the root cause of the crack appearance. Airbus Helicopters thus makes it mandatory not to push on the rear part of the LH and/or RH rear support covers when closing the door. Compliance with this ALERT SERVICE BULLETIN consists in checking the LH and/or RH rear supports to make sure that there are no cracks, before adding a label that prohibits any pushing in this area.
