EASA AIRWORTHINESS DIRECTIVE

AD No.: 2012-0183R1

Date: 28 September 2012

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with 

Regulation (EC) No 216/2008 on behalf of the European Community, its Member States and of 

the European third countries that participate in the activities of EASA under Article 66 of that 

Regulation.

This AD is issued in accordance with EC 748/2012, Part 21.A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the 

continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may operate 

an aircraft to which an AD applies, except in accordance with the requirements of that AD, unless otherwise specified by the Agency 

[EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemption].

Design Approval Holder’s Name:

328 Support Services GmbH

Type/Model designation(s):

328-100 and 328-300 aeroplanes

TCDS Number: EASA A.096

Foreign AD: Not applicable

Revision: This AD revises EASA AD 2012-0183 dated 12 September 2012, which 

superseded EASA AD 2007-0199 dated 25 July 2007, including the Correction 

dated 26 July 2007.

ATA 52 Doors – Passenger Door Hinge Supports – Modification

Manufacturer(s): Dornier Luftfahrt GmbH; Fairchild-Dornier GmbH; AvCraft Aerospace GmbH

Applicability: Dornier 328-100 aeroplanes, serial numbers 3005 through 3101, 3103, 3104, 

3106, 3109, 3110, 3112, 3113, 3115, 3117 and 3119; and

Dornier 328-300 aeroplanes, all serial numbers.

Reason: At least one incident occurred where, immediately after take-off, the 

passenger door of a Dornier 328 aeroplane completely opened. The flight 

crew reportedly had no cockpit indication or audible chime prior to this event. 

The aeroplane returned to the departure airfield and made an uneventful 

emergency landing. Substantial damage to the door, handrails, door hinge 

arms and fuselage skin were found.

The subsequent investigation could not find any deficiency in the design of the 

main cabin door locking mechanism. In addition, no technical failure could be 

determined that precipitated the event. The flight data recorder showed that 

the door was closed and locked before take-off and opened shortly 

afterwards. Although final proof could not be obtained, the most likely way in 

which the door opened was that the door handle was inadvertently operated 

during the take-off run.

In response to the incident, AvCraft (the TC holder at the time) developed a 

placard set to warn the occupants against touching the door handle, as well 

as a structural modification of the passenger door hinge supports described in 

Service Bulletin (SB) SB-328-52-460 and SB-328J-52-213 to make certain 

that the door does not separate from the aeroplane when inadvertently

opened during flight, allowing a safe descent and landing.

EASA issued AD 2007-0199 to require the installation of warning placards 

and modification as detailed in these SB instructions.

Since that AD was issued, 328 Support Services GmbH (the current TC 

holder) have determined that certain fasteners, identified by Part Number 

(P/N) NAS6703U1 and P/N NAS6703U2, which were installed as part of the 

modification, have the wrong length and must be replaced.

For the reasons described above, this AD retains the requirements of EASA 

AD 2007-0199, which is superseded, and requires replacement of the affected 

fasteners by the ones that have the correct length.

This AD has been revised to correct and clarify the actions required by 

paragraph (3).
