Federal Aviation Administration February 15, 2011 – Federal Register Recent Federal Regulation Documents

We propose to supersede an existing airworthiness directive (AD) that applies to certain fuel injected reciprocating engines manufactured by Lycoming Engines. The existing AD currently requires inspection, replacement if necessary, and proper clamping of externally mounted fuel injector fuel lines. That AD also exempts engines that have a Maintenance and Overhaul Manual with an Airworthiness Limitations Section that requires inspection and replacement, if necessary, of externally mounted fuel injector lines. This proposed AD would require the same actions. Since we issued that AD, Lycoming Engines revised their Mandatory Service Bulletin (MSB) to add engine models requiring inspections. We are proposing this AD to prevent failure of the fuel injector fuel lines that would allow fuel to spray into the engine compartment, resulting in an engine fire.

This action clarifies a reciprocal waiver of claims requirement for an FAA authorized launch or reentry in which a licensee or permittee has multiple customers. There has been confusion about whether all customers must sign or whether one customer can sign such an agreement on behalf of all customers. This action eliminates any confusion by clarifying that a reciprocal waiver of claims requires each customer to enter into a waiver with the U.S. Government and the licensee or permittee. However, this action does not change the existing practice for government customers, which is that the FAA signs on their behalf.

This action revises Class E airspace at Wiley Post/Will Rogers Memorial Airport in Barrow, AK, in order to accommodate the amendment of five Standard Instrument Approach Procedures (SIAPs), and one Obstacle Departure Procedure (ODP) and to enhance safety and management of Instrument Flight Rules (IFR) operations.

This action revises Class E airspace at Shungnak, AK, to accommodate amended Standard Instrument Approach Procedures (SIAPs) at the Shungnak Airport. The FAA is taking this action to enhance safety and management of Instrument Flight Rules (IFR) operations at the Shungnak Airport.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: * * * * * The airworthiness limitations applicable to Damage Tolerant Airworthiness Limitation Items (DT ALI) are currently given in Airbus A340 ALI Document reference AI/SE-M4/95A.0051/97, which is approved by the European Aviation Safety Agency (EASA) and referenced in Airbus Airworthiness Limitations Section (ALS) Part 2. The issue 11 of Airbus A340 ALI Document introduces more restrictive maintenance requirements/airworthiness limitations. Failure to comply with this issue 11 constitutes an unsafe condition. This new [EASA] AD retains the requirements of EASA AD 2007- 0158, which is superseded, and requires the implementation of the more restrictive maintenance requirements/airworthiness limitations as specified in Airbus A340 ALI Document AI/SE-M4/95A.0051/97 issue 11.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

We are adopting a new airworthiness directive (AD) for certain Model 767 airplanes. This AD requires doing a detailed inspection for correct main track downstop assembly, thread protrusion, and damaged and missing parts of the main track downstop assemblies of the outboard slats, and related investigative and corrective actions if necessary. This AD also requires doing a detailed inspection for foreign objects, debris and damage to the wall of the track housing of the outboard slats, and corrective actions if necessary. This AD results from reports of broken bolts in the outboard slat main track downstop assembly. We are issuing this AD to detect and correct incorrectly installed main track downstop assemblies, which can allow the main track downstop hardware to fall into the track housing and cause a puncture in the track housing when the slat is retracted. This condition, if not corrected, could result in a fuel leak and an increased risk of fire.
