Applicability:

Aeroplane models and serial numbers listed in Table 1 that have any circuit breaker toggle switch with a part number (P/N) 35-380132-1 through 35-380132-53 installed.

Table 1

Model

Serial Number Range

A36
A36TC and B36TC

E-185 through E-3629 and E-3631 through E-3635
EA-1 through EA-695

Requirement:

1. Unless previously accomplished, replace all circuit breaker toggle switches P/N 35-380132-1 through 35-380132-53 with an improved circuit breaker toggle switch, P/N 35-380132-61 through 35-380132-113, as applicable, as specified in Raytheon Aircraft Company (RAC) Recommended Service Bulletin SB 24-3735, Issued: August 2005.

2. Circuit breaker toggle switches P/N 35-380132-1 through 35-380132-53 may not be installed on any aeroplane as an initial fit or as a replacement spare.

Later revisions of the above SB, approved by the United States Federal Aviation Administration (FAA) as an Alternate Method of Compliance (AMOC) to FAA AD 2008-13-17, are considered acceptable for compliance with the equivalent Requirements of this Directive.

Note: FAA AD 2008-13-17 Amdt 39-15580 refers.

Compliance:

For Requirement 1 - Within the next 24 months after the effective date of this Directive.

For Requirement 2 - Before further flight after the circuit breaker toggle switch has been replaced in accordance with Requirement 1.

This Airworthiness Directive becomes effective on 25 September 2008.

\n```\n\n| Background: | The FAA has received reports of certain circuit breaker toggle switches used in various electrical systems throughout Beech F33, F33A, F33C, G33, V35B, A36, A36TC, B36TC, 95-B55, D55, E55, A56TC, 58, 58P, 58TC, G58 and 77 model aeroplanes overheating. Failure of the circuit breaker toggle switch could result in smoke in the cockpit and the inability to turn off the switch. |\n| ----------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| | This Directive follows the intent of the FAA Directive, requiring the replacement of circuit breaker toggle switches with a P/N 35-380132-1 through 35-380132-53. However, it is revised to allow prior accomplishment, as the RAC service bulletin was issued in 2005 and may have already been accomplished. The Directive also extends compliance by 13 months until 25 September 2010, the final compliance time required by the FAA was 6 August 2009. |\n| | A draft version of this Directive was posted for public comment on the Civil Aviation Safety Authority (CASA) internet site on 9 July 2008. As of the date that this Directive was made, no comments or objections have been received by CASA. |\n\n![](image.001.png)\n\nJames Coyne \nDelegate of the Civil Aviation Safety Authority\n\n8 August 2008","sortOrder":0},{"sectionNumber":"AD/BEECH 36/52","sectionType":"part","heading":"AD/BEECH 36/52","content":"## AD/BEECH 36/52","sortOrder":1},{"sectionNumber":"Circuit Breaker Toggle Switches","sectionType":"part","heading":"Circuit Breaker Toggle Switches","content":"## Circuit Breaker Toggle Switches","sortOrder":2},{"sectionNumber":"10/2008","sectionType":"part","heading":"10/2008","content":"## 10/2008","sortOrder":3}],"analysis":{"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":true,"description":"This Directive follows the FAA AD's intent to replace the specified circuit breaker toggle switches but changes timing and scope mechanics: it explicitly allows prior accomplishment of the service bulletin and extends the compliance window by 13 months (CASA text: ‘revised to allow prior accomplishment’ and ‘extends compliance by 13 months until 25 September 2010’), while retaining the replacement and prohibition requirements and acceptance of FAA‑approved AMOCs."},"complexity_factors":["Specific applicability to listed models and serial-number ranges (Table 1) increases administrative checking of affected aircraft.","Precision of part-number ranges to be removed (P/N 35-380132-1 through -53) and installed (P/N 35-380132-61 through -113) requires parts-level compliance.","Mandated use of Raytheon Aircraft Company Recommended Service Bulletin SB 24-3735 introduces dependency on an external technical document.","Acceptance of later SB revisions only if approved by FAA as an AMOC adds regulatory dependency and potential need for approval tracking.","Two distinct requirements: replace within time limit and prohibit installation of old P/N as initial fit or spare, creating an ongoing spare-parts compliance obligation.","Compliance timing: a 24-month window from the directive effective date (administrative scheduling and maintenance planning).","Allowance for prior accomplishment requires record verification to confirm compliance and avoid redundant work."],"plain_english_summary":"Requires owners of listed Beechcraft 36-series aeroplanes with circuit breaker toggle switches P/N 35-380132-1 through -53 to replace them with improved switches P/N 35-380132-61 through -113 per Raytheon Service Bulletin SB 24-3735, within 24 months of the directive (effective 25 Sept 2008).
