AD 2007-13-06 Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Airplanes

Models named: BAe 146-100A, -200A, -300A series, Avro 146-RJ70A, 146-RJ85A, 146-RJ100A. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to BAE Systems (Operations) Limited Model BAe 146-100A, -200A, and -300A series airplanes, and Model Avro 146-RJ70A, 146-RJ85A, and 146-RJ100A airplanes; certificated in any category; which have modification HCM00674A embodied. Reason (d) The mandatory continuing airworthiness information (MCAI) states: There are four ECS (environmental control system) grilles located in the flight deck side consoles. There have been occurrences where a grille has become detached during flight. There is a risk that a loose grille could foul the rudder pedals and interfere with rudder/brake control resulting in an unsafe condition. The unsafe condition is a rudder pedal restriction or jam, which could result in reduced controllability of the airplane. The MCAI requires modifying the grilles.

Within 6 months after the effective date of this AD, unless already done, carry out the modification of the ECS grilles as described in BAE Systems (Operations) Limited Modification Service Bulletin SB.25-495- 60730A, dated March 14, 2006; or Revision 1, dated May 9, 2006.
