Airworthiness Directives; Airbus Model A300, A310, and A300-600 Series Airplanes

Tue, Jun 17 2008 11:00:00 GMT

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A300, A310, and A300600 series airplanes. The existing AD currently requires repetitive detailed visual inspections to detect cracks in the pylon thrust and sideload fitting of the wing, and replacement of any cracked pylon thrust and sideload fitting with a new fitting. This proposed AD would

reduce the threshold and repetitive intervals for the detailed inspection for certain airplanes and would reduce the applicability of the existing AD. This proposed AD results from issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. We are proposing this AD to detect and correct cracks in the pylon thrust and sideload fitting of the wing, which could result in reduced structural integrity of the airplane.

Airworthiness Directives; Airbus Model A330 Airplanes; and Model A340-200 and -300 Airplanes

We are revising an original NPRM for the products listed above. This action revises the original NPRM by expanding the scope. This proposed 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 aim of * * * [Special Federal Aviation Regulation (SFAR) 88] is to require all holders of type certificates * * * to carry out a definition review against explosion hazards.
The unsafe condition is the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

Airworthiness Directives; Boeing Model 767-200 and -300 Series Airplanes

This document revises an earlier proposed airworthiness directive (AD), applicable to certain Boeing Model 767200 and 300 series airplanes. That proposed rule would have required replacing certain doormounted escape slides and slideraft assemblies with new slideraft assemblies; replacing certain escape system latches with new latches; and modifying or replacing certain counterbalance assemblies with new counterbalance assemblies; as applicable. This new action revises the proposed rule by extending the compliance time, adding requirements to install a longer firing cable and test the valve of the inflation trigger system of the slideraft, and, for certain airplanes, adding procedures to adjust the door counter balance systems. The actions specified by this new proposed AD are intended to prevent the escape slides and sliderafts of the forward and midcabin entry and service doors from being too steep for evacuation in the event that the airplane rotates onto the aft fuselage into the extreme tip
