This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Models A65, A65-8200, 65-B80, 70, 95-A55, 95-B55, 95-C55, D55, E55, 56TC, A56TC, 58, 58P, 58TC, 95-B55B (T42A) airplanes. This AD requires replacement of certain elevator skin assemblies that Raytheon shipped from January 1, 1999, through December 31, 1999, and prevents the future installation of these elevator skin assemblies. This AD authorizes the pilot to check the logbooks to determine whether one of these elevator skin assemblies is installed. This AD is the result of reports that certain elevator skin assemblies did not receive a 250-degree Fahrenheit bake operation after corrosion treatment, thus making the skin susceptible to separation from the elevator assembly. The actions specified by this AD are intended to detect and correct potential elevator skin separation, which would lead to a reduction in static strength capability with continued operation. This could then result in potential airplane flutter with consequent loss of control of the airplane.
To address this problem, you must accomplish the following actions:
| Action | Compliance time | Procedures |
|---|---|---|
| (1) Maintenance Records Check: | ||
| (i) The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may check the maintenance records to determine whether one of the affected elevator skin assemblies (particular part numbers referenced in the applicable service information) was installed after December 31, 1998 | Required within 1 month after September 22, 2000 (the effective date of this AD) | No special procedures required to check the logbook. Raytheon Mandatory Service Bulletin SB 27-3396, Rev. 1, Issued: May, 2000; Revised: June, 2000, references this maintenance records check. |
| (ii) If, by checking the maintenance records, the pilot can positively show that one of the elevator skin assemblies (particular part numbers referenced in the applicable service information), is not installed or was installed prior to January 1, 1999, then the replacement requirement of paragraph (d)(2) of this AD does not apply. You must make an entry into the aircraft records that shows compliance with this portion of the AD, in accordance with section 43.9 of the Federal Aviation Regulations (14 CFR 43.9) | ||
| (2) Replacement: Replace any elevator skin assembly (particular part numbers referenced in the applicable service information) that Raytheon shipped anytime from January 1, 1999, through December 31, 1999. Paragraphs (d)(1)(i) and (d)(1)(ii) of this AD provide procedures for checking the maintenance records to determine if one of the affected elevator skin assemblies is installed | Within 1 month after September 22, 2000 (the effective date of this AD) | Accomplish this replacement in accordance with the ACCOMPLISHMENT INSTRUCTIONS section of Raytheon Mandatory Service Bulletin SB 27-3396, Rev. 1, Issued: May, 2000; Revised: June, 2000. |
| (3) Installation Prohibition: You may not install any elevator skin assembly (particular part numbers, referenced in the applicable service information) that Raytheon shipped anytime from January 1, 1999, through December 31, 1999, in any of the affected airplanes | As of September 22, 2000 (the effective date of this AD) | Not Applicable. |
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.
