### ATA 52 Doors

– Sliding Door Star S upport

– Modification

Manufacturer(s): Airbus Helicopters (formerly Eurocopter

, Eurocopter

- France)

Applicability: EC 120 B helicopters, all Serial Numbers (S/N), equipped with sliding door Part Number ( P/N ) C526A2370101, except those helicopters that have incorporated modification (MOD) A00565 (reinforcement of the sliding door star support attachment)

, and

EC 130 B4 helicopters, all S/N, equipped with sliding door P/N C526S1101051, except those helicopters t hat have incorporated MOD 07 3796 (reinforcement of the sliding door star support attachment), or have incorporated Eurocopter MOD 07 2921 (industrialized sliding door)

.

Reason: A case has been reported where, after landing

, the passengers of an Eurocopter helicopter could not open the sliding door from inside. The passengers had to leave the helicopter through the pilot door. The investigation revealed a sliding
door star axle support failure.

This condition, if not corrected, could delay the eva cuation from the helicopter in case of emergency, possibly resulting in injury to the occupants.

To address this potential unsafe condition, Eurocopter published EC120 Alert Service Bulletin ( ASB ) No

. 52A014 and EC130 ASB No.52A009 (both Revision 1) to provide modification instructions.

Consequently

, EASA issued AD 2013

- 0093 to require modification of the sliding door star support.E ASA AD No.: 20 15

52A014 to revise and correct the applicability

, to extend it to all s/n helicopters with the affected P/N door, except those in a specific MOD configuration

. For the reason described above, t his AD retains the requirements of EASA AD
