What this AD requires

The FAA is adopting a new airworthiness directive (AD) for The Boeing Company Model 737-300, -400, and -700 series airplanes, modified to a Bedek Division Special Freighter (BDSF) by Supplemental Type Certificate (STC) ST01566LA, ST01961SE, or ST02556SE, with a 9G rigid barrier. An emergency AD was sent to all known U.S. owners and operators of these airplanes. This AD requires complying with loading restrictions and methods. This AD was prompted by a review of the manufacturing process for the 9G rigid barrier installed on BDSF conversions that identified a manufacturing non-compliance. The FAA is issuing this AD to address the unsafe condition on these products.

Models737-300, 737-400, 737-700, 737

Part-conditional — ST01566LA, ST01961SE, ST02556SE.

Applies only to airplanes modified to a Bedek Division Special Freighter (BDSF) configuration by STC ST01566LA, ST01961SE, or ST02556SE, with a 9G rigid barrier installed.

Whether AD 2019-25-55 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 2019-25-55 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.
