Is AD 03-17019 a recurring Airworthiness Directive?

No — AD 03-17019 is a one-time directive. Verify it was complied with in the aircraft's records.

Airworthiness Directives; Textron Lycoming Fuel Injected Reciprocating Engines

What this AD requires

This amendment supersedes an existing airworthiness directive (AD), that is applicable to certain Textron Lycoming reciprocating engines with certain Crane/Lear Romec "AN" rotary fuel pumps installed. That AD currently requires initial and follow-up torque check inspections of pump relief valve attaching screws. This amendment requires the same initial and follow-up torque check inspections of relief valve attaching screws, and adds as a terminating action, replacement of the affected fuel pump at or before the overhaul interval, with a fuel pump having a new design valve housing. This amendment is prompted by the introduction of a new design pump relief valve housing and associated parts that provide enhanced resistance to fuel leakage, and the need for clarification of the requirements of the current AD. The actions specified by this AD are intended to prevent rotary fuel pump leaks, which could result in an engine failure, engine fire, and damage to or loss of aircraft.

Applies only to the listed fuel-injected reciprocating engines with a Crane/Lear Romec RG9080, RG9570, or RG17980 series 'AN' rotary fuel pump (per the Lycoming/Lear-Romec cross-reference table) installed.

Whether AD 03-17019 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:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
