Airworthiness Directives; Hawker Beechcraft Corporation Model 390 Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation (HBC) Model 390 airplanes. This AD requires you to inspect hydraulic pump pressure output hose assemblies to determine if they are from the affected lots, inspect for hydraulic fluid leaks if the hose assemblies are from the affected lots, and replace all affected hose assemblies. This AD results from reports of hydraulic leaks from the hydraulic pump pressure output hose assemblies. We are issuing this AD to prevent leakage of hydraulic fluid from the pump output hose within the engine compartment, which could result in an in-flight fire.

Serial-conditional — narrows to serials RB-1–RB-1, RB-4–RB-209, RB-210–RB-239.

Part-conditional — 390-5805-0001.

S/Ns RB-1 and RB-4 through RB-209 apply only if equipped with hose kit 390-5805-0001 installed during compliance with Hawker Beechcraft Mandatory Service Bulletin 29-3800 (dated May 2007); S/Ns RB-210 through RB-239 apply unconditionally. Concerns hydraulic leaks from hydraulic pump pressure output hose assemblies.

Whether AD 2008-22-11 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 2008-22-11 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.
