As reported to the FAA. Reports are unverified, and codes are left as the FAA publishes them.

What was found

(CAN) 2 OIL FILTERS WERE FOUND INSTALLED IN GEARBOX. FILTERS ARE NOT GENUINE, NOT APPROVED AND WERE NEVER RELEASED UNDER THE ENGINE / GEARBOX TYPE DESIGN. THE FILTER SHOWS AN IC NUMBER WHILE IT SHOULD INDICATE THE VENDOR P/N AND THE FILTERING CAPACITY. THE SEATING FLANGE DOES NOT MATCH THE ORIGINAL DESIGN SINCE IT IS BUILD FROM 2 ALUMINUM PIECES THAT ARE SPOT WELDED TOGETHER. PWC HAS PLACED THIS PART IN QUARANTINE FOR 21 DAYS.
