Is AD 2019-01-03 a recurring Airworthiness Directive?

Yes — AD 2019-01-03 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2019-01-03 apply to?

AD 2019-01-03 applies to The Boeing Company — models 737-600, 737-700, 737-700C, 737-800, 737-900, 737-900ER, 737. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; the Boeing Company Airplanes

What this AD requires

We are superseding Airworthiness Directive (AD) 2016-18-01, which applied to certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. AD 2016-18-01 required repetitive lubrication of the forward and aft trunnion pin assemblies of the right and left main landing gears (MLGs); repetitive inspection of these assemblies for corrosion and chrome damage, and related investigative and corrective actions if necessary; and installation of new or modified trunnion pin assembly components, which terminated the repetitive lubrication and repetitive inspections. Since we issued AD 2016-18-01, we have determined that rotable parts were not addressed in that AD, and it is therefore necessary to include all airplanes of the affected models in the applicability. This AD retains the requirements of AD 2016-18-01, adds airplanes to the applicability, and prohibits the installation of a MLG or MLG trunnion pin assembly under certain conditions. We are issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Applicability subdivided by group/configuration per Boeing Special Attention Service Bulletin 737-32-1448, Revision 2, dated August 2, 2017: Groups 1-2 Configuration 1; Groups 1-2 Configuration 2; Group 3; Groups 4-5 Configuration 1; Groups 4-5 Configuration 2; Group 6 (for these last three, line number 3527 through the line number of an airplane with an original/export Certificate of Airworthiness dated on or before the AD effective date); and all covered models with an original/export Certificate of Airworthiness dated after the AD effective date. Installation of STC ST00830SE does not affect applicability or AMOC requirements.

Whether AD 2019-01-03 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.

Is AD 2019-01-03 complied with on your aircraft?

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.
