AIRWORTHINESS DIRECTIVE NO: 1-127
AIRCRAFT TYPE: SAAB SF 340A and SAAB 340B
SERIAL No’s: SAAB SF 340A -004 through -159
AFFECTED: SAAB 340B -160 through -439
SUBJECT: Landing Gear - Brakes - Inspection of the installation combination of the brake assemblies
BACKGROUND: Together with the introduction of the new ABSC 5012589-3 brake (SB 340-32-113), a restriction regarding the installation combination was found necessary.
Further investigations have shown that additional restrictions are necessary in order to avoid an unbalanced aircraft handling situation and degradation of brake performance. Only symmetrical brake installation configurations are permitted. Therefore this SAD requires inspection and if necessary replacement of the brakes to achieve a symmetrical brake configuration on the aircraft.
