Summary
This document revises an earlier proposed airworthiness directive (AD), applicable to certain Airbus Model A300 B2 and B4 series airplanes; Model A300 B4-600, A300 B4-600R, and A300 F4-600R series airplanes (collectively called A300-600); Model A310 series airplanes; Model A319, A320, and A321 series airplanes; Model A330-301, -321, -322, -341, and -342 series airplanes; and Model A340 series airplanes; that would have required, among other actions, replacement of certain pitot probes with certain new pitot probes. This new action would revise the replacement procedures of the proposed AD by requiring enlargement of the holes for the pitot probes. The actions specified by this new proposed AD are intended to prevent loss or fluctuation of indicated airspeed, which could result in seriously misleading information being provided to the flightcrew. This action is intended to address the identified unsafe condition.
