Superseded. A later AD replaced this one: AD 2000-03-06. Comply with the one in force.
SE3130, SA3180, SE313B, SA318B, and SA318C helicopters with horizontal stabilizer, part number (P/N) 3130-35- 60-000, 3130-35-60-000-1, 3130-35-60-000-2, 3130-35-60-000-3, 3130- 35-60-000-4 or higher dash numbers, installed, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to Eurocopter France Model SE3130, SA3180, SE313B, SA318B, and SA318C helicopters, that requires an initial and repetitive visual inspections and modification, if necessary, of the horizontal stabilizer spar tube (spar tube). This amendment is prompted by an in- service report of fatigue cracks that initiated from corrosion pits. The actions specified by this AD are intended to prevent fatigue failure of the spar tube, separation and impact of the horizontal stabilizer with the main or tail rotor, and subsequent loss of control of the helicopter.
