Airworthiness Directive 02-86
one-timeAirworthiness Directives; McDonnell Douglas Model DC-9-10, -20, -30, and -40 Series Airplanes and C-9 Airplanes
What this AD requires
This document corrects information in an existing airworthiness directive (AD) that applies to certain McDonnell Douglas Model DC-9-10, -20, -30, and -40 series airplanes and C-9 airplanes. That AD currently requires modification of the spoiler control system, and installation of protective interlock box assemblies in the spoiler circuit. This document corrects the affected models specified in the "Applicability" of the AD. This correction is necessary to ensure that the appropriate affected airplane models are identified correctly.
Which aircraft AD 02-86 applies to
Whether AD 02-86 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.
