### ATA 63 Rotor Drive(s) – Lubricating System / Oil Ou tlet Hose – Inspection

Manufacturer(s): AgustaWestland S.p.A. (formerly Ag usta S.p.A.)

Applicability: AB 212, AB 412 and AB412EP helicopte rs, all manufacturer serial numbers

Reason: Two occurrences were reported to AgustaWest land, describing oil leakage of a main transmission lubricating system oil outlet hos e part number (P/N) 70-061L275W210A, due to damage of the oil hose. Sub sequent investigation has not yet determined the root cause, however a re lative movement between the data plate and hose assembly was identified as a possible contributing factor to the occurrence.
This condition, if not detected and corrected, coul d lead to transmission lubricating system failure, resulting in reduced co ntrol of a helicopter. To address this potential unsafe condition, AgustaW estland issued Bollettino Tecnico (BT) 212-204 for AB 212 helicopters, and BT 412-137 for AB 412 and AB 412EP helicopters, to provide inspection instruc tions.
For the reasons described above, this AD requires r epetitive inspections of affected oil outlet hose, and depending on findings , replacement of oil outlet hose. This AD is considered to be a temporary measu re and further mandatory actions may follow.
