Airworthiness Directive 99-25765
one-timeAirworthiness Directives; Raytheon (Beech) Model 400A Airplanes
What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to certain Raytheon (Beech) Model 400A airplanes, that requires replacement of the fuel drain tube assembly in the aft fuselage with a new, modified assembly. This amendment is prompted by a report of chafing of the fuel tube assembly against the elevator control cable due to inadequate clearance between the components. The actions specified by this AD are intended to prevent chafing of the fuel drain tube assembly, which could result in fuel leakage from the fuel drain tube assembly and consequent risk of a fire.
Which aircraft AD 99-25765 applies to
Extracted text begins at the standard 'preceding applicability provision' boilerplate; the AD's actual airplane model list precedes this excerpt and was not captured by extraction. Prevents chafing of the aft fuselage fuel drain tube assembly, P/N 128-920151-1, which could cause fuel leakage and fire risk. Requires replacement with a modified tube assembly, P/N 128-920237-1, at the next scheduled inspection or no later than 200 flight hours after the effective date, per Raytheon Aircraft Service Bulletin SB.28-3076, dated October 1997. No person may install the superseded P/N 128-920151-1 as of the effective date.
Whether AD 99-25765 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.
