Airworthiness Directive 00-19262
one-timeAirworthiness Directives; Boeing Model 727-100 and -200 Series Airplanes Equipped With an Engine Nose Cowl for Engine Numbers 1 and 3, Installed in Accordance With Supplemental Type Certificate (STC) SA4363NM
What this AD requires
This amendment revises an existing airworthiness directive (AD), applicable to certain Boeing Model 727-100 and -200 series airplanes, that currently requires replacing the attaching nutplates on certain engine nose cowls with washers and self-locking nuts. This amendment changes the responsible office for approval of an alternative method of compliance. This amendment is prompted by the transfer of the supplemental type certificate. The actions specified in this AD are intended to prevent the attach bolts from becoming loose, which could result in subsequent separation of the nose cowl from the engine.
Which aircraft AD 00-19262 applies to
Requires replacing No. 1 and No. 3 engine nose cowl attaching nutplates with washers/self-locking nuts per VALSAN B727-RE Service Bulletin 71-006 Rev 1; as of Oct 20, 1995, prohibits installing a nose cowl with VALSAN P/N 259-0002-501 or 259-0002-503 on any airplane.
Whether AD 00-19262 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.
