Airworthiness Directive 2001-19-06
one-timeAirworthiness Directives; Rolls-Royce plc Dart 525, 525F, 528, 528D, 529, 529D, 530, 532, 535, 542, and 552 Series Turboprop Engines
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to Rolls-Royce plc (RR) Dart 525, 525F, 528, 528D, 529, 529D, 530, 532, 535, 542, and 552 series turboprop engines. This action requires the removal of certain part number (P/N) high pressure turbine (HPT) discs and replacement with serviceable discs. This amendment is prompted by three reports of uncontained HPT disc failures and the manufacturer's investigation into disc failure. The actions specified in this AD are intended to prevent HPT disc failure, which could result in an uncontained engine failure and damage to the airplane.
Which aircraft AD 2001-19-06 applies to
Applies to Rolls-Royce Dart turboprop engines fitted with HPT discs identified by part number in Table 1 of the AD (table contents not included in this excerpt); removal schedule keyed to cycles-since-new per Table 2, with reworking to serviceable status per RR Dart SB Da72-533 Rev 2.
Whether AD 2001-19-06 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
