Airworthiness Directive · Amendment 39-11925 · Raytheon Aircraft Company Beech Models A36 and B36TC Airplanes
Raytheon Aircraft Company Beech Models A36 and B36TC Airplanes
This AD affects the following airplanes, certificated in any category:
Beech Model A36: Serial numbers E-3113 through E-3231, E-3233 through E-3263, E-3265 through E-3267, E-3269, E-3271, E-3273, and E3277.
Beech Model B36TC: Serial numbers EA-594 through EA-644.
This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Corporation (Raytheon) Beech Models A36 and B36TC airplanes. This AD requires you to inspect for the installation of firewall sealant and install firewall sealant if not present. This AD is the result of a report that firewall sealant was not found during a routine production inspection. The actions specified by this AD are intended to correct the absence of sealant and prevent the consequent entry of smoke or fire into the flight compartment or cabin in the event of an engine compartment fire.
To address this problem, you must accomplish the following actions:
| Actions | Compliance time | Procedures |
|---|---|---|
| (1) Inspect for sealant between the faying surfaces of the part number (P/N) 109-361023-13 tube assembly fitting and the P/N 36-430054-69 upper firewall panel | Inspection required within 50 hours time-in-service after November 28, 2000 (the effective date of this AD), and sealant application required before further flight after the inspection | Accomplish all actions in accordance with the ACCOMPLISHMENT INSTRUCTIONS section of Raytheon Mandatory Service Bulletin SB 53-3375, Issued: December 1999. |
| (i) If sealant is present, no further action is necessary | ||
| (ii) If sealant is not present, apply sealant to the tube assembly and the upper firewall panel. |
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
