Start Preamble

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:

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
Modify passenger doors [retained actions from AD 2008-14-16, Amendment 39-15611 (73 FR 40955, July 17, 2008)]38 work-hours × $85 per hour = $3230$11,961$15,191$531,685
Replace fasteners [new proposed action]25 work-hours × 85 per hour = 2,12502,12574,375

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 Start Printed Page 52874that 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.
