RIN 2120-AA64

Airworthiness Directives; 328 Support Services GmbH (Type 
Certificate Previously Held by AvCraft Aerospace GmbH; Fairchild 
Dornier GmbH; Dornier Luftfahrt GmbH) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to supersede airworthiness directive (AD) 2008-14-
16 that applies to certain 328 Support Services GmbH (Type Certificate 
Previously Held by AvCraft Aerospace GmbH; Fairchild Dornier GmbH; 
Dornier Luftfahrt GmbH) Model 328-100 and 328-300 airplanes. AD 2008-
14-16 currently requires installing warning placards on the inside of 
the passenger door and service doors and modifying the hinge supports 
and support struts of the passenger doors. Since we issued AD 2008-14-
16, we received reports that certain fasteners, which were installed as 
part of the modification, are the wrong length. This proposed AD would 
require replacing the fasteners which were installed as part of the 
modification with new fasteners of the correct length, adds new 
airplanes, and removes one airplane. We are proposing this AD to 
prevent incidents of inadvertent opening and possible detachment of a 
passenger door in-flight, resulting in damage to airframe and systems 
and loss of control of the airplane.

DATES: We must receive comments on this proposed AD by October 11, 
2013.

Discussion

    On July 17, 2008, we issued AD 2008-14-16, Amendment 39-15611 (73 
FR 40955, July 17, 2008). AD 2008-14-16 required actions intended to 
address an unsafe condition on 328 Support Services GmbH (Type 
Certificate Previously Held by AvCraft Aerospace GmbH; Fairchild 
Dornier GmbH; Dornier Luftfahrt GmbH) Model 328-100 and Model 328-300 
airplanes.
    Since we issued AD 2008-14-16, Amendment 39-15611 (73 FR 40955, 
July 17, 2008), we received reports that certain fasteners which were 
installed as part of the modification are the wrong length and need to 
be replaced. The European Aviation Safety Agency (EASA), which is the 
aviation authority for the Member States of the European Community, has 
issued EASA Airworthiness Directive 2012-0183R1, dated September 28, 
2012 (referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

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 [Dornier 328 Support Services] 
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 [2007-0199] was issued, 328 Support Services GmbH (the 
current type certificate 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 [EASA] 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 [EASA] AD has been revised to correct and clarify the actions 
required by paragraph (3).

This AD also adds new airplanes and removes one airplane from the 
applicability of this AD. You may obtain further information by 
examining the MCAI in the AD docket.

Relevant Service Information

    328 Support Services GmbH has issued 328 Support Services Service 
Bulletin SB-328-52-460, Revision 2, dated March 1, 2012 (for Model 328-
100 airplanes); and Dornier 328 Support Services Service Bulletin SB-
328J-52-213, Revision 1, dated August 17, 2011 (for Model 328-300 
airplanes). The actions described in this service information are 
intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 35 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition

[[Page 52874]]

that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national Government and the States, or on the distribution 
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

local flight standards district office/certificate holding district 
office. The AMOC approval letter must specifically reference this 
AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
