Embraer EMB-110 (Bandeirante) Series Aeroplanes

AD/EMB-110/2

Amdt 9

Fatigue Life Limits 9/2002 TX

Applicability: All Model EMB-110 aircraft.

Requirement: Except for the variations noted below, retire from service before exceeding the

service lives shown in the table the landing gear, fuselage and wing components listed in Section IV, Table A, “Life Limits”, of Embraer Technical Manual No TP 110P2/145, EMB-110 Bandeirante “Maintenance Planning Guide”, Original issue dated 12 July 1988, as revised by Change 16 dated 29 May 2002.

The Authority has approved a life increase, to 50,000 landings for main landing gear piston tubes part number 14333-000-01/02. The increased life is effective from 29 November 2000. The Authority has asked Embraer to change the MPG.

Change 15 to the MPG dated 30 March 2002, introduces a life limit of 21 000 hours TIS for the engine mounts, which had not previously been lifed. Because of the effect that this change will have on operators, Embraer have developed an implementation plan which will ensure that operators comply with the new life limit by 30 November 2002 (Embraer letter PCE-2157/2002 of 10 July 2002 refers). The Authority has accepted Embraer’s implementation plan. Accordingly, aircraft with engine mounts which have accumulated more than 21 000 hours TIS are to have their engine mounts replaced by 30 November 2002 in accordance with the implementation plan contained in Embraer letter PCE-2157/2002 of 10 July 2002.

Note1: Whenever the MPG specifies the service life in both hours and landings for a component, that component shall be retired at the earlier of the two limits reached in each instance.

Note 2: Correct installation is critical to the durability of the improved design wing attachment fittings, part number 110-2111-00-78, 110-2211-00-78, 110-1231-50-41, and 110-1231-50-42. The lives in the MPG apply to fittings installed by either the aircraft manufacturer or Eastern Australia Airlines (EOs WIF 001, WIF 002).
