| AD/CL-600/95 | Air-Driven Generator - Internal Wiring | 4/2008 DM |
|---|
| Applicability: | Model CL-600-2B19 aeroplane with serial numbers (S/N) 7305 through 7990, 8000 and subsequent. |
|---|---|
| Requirement: | 1. For aeroplanes with S/N 7305 through 7990 and 8000 through 8083 - |
| a. Inspect the S/N of the installed air driven generator (ADG). If the S/N is not listed in paragraph 1.A of Bombardier Aerospace Service Bulletin (SB) 601R-24-113, Revision A, dated 11 August 2005, or later revision approved by the Chief, Continuing Airworthiness, Transport Canada, no further action is necessary. | |
| b. If as a result of the Requirement 1.a. inspection it is determined that the ADG S/N is listed in the SB inspect the ADG identification plate. If it is marked with the symbol “24-2” (refer Hamilton Sundstrand SBERPS10AG-24-2), no further action is necessary. | |
| c. If the ADG identification plate is not marked with the symbol “24-2” modify the ADG wiring in accordance with the Accomplishment Instructions in SB 601R-24-113, Revision A, or later revision approved by the Chief, Continuing Airworthiness, Transport Canada. | |
| Note 1: Previous inspection, and modification as required, in accordance with Bombardier Aerospace SB 601R-24-113, original issue, dated 22 April 2004, or Revision A, dated 11 August 2005, is considered satisfactory for compliance with Requirement 1 of this directive if the ADG has not been replaced since SB incorporation. | |
| Note 2: It is permissible to satisfy Requirement 1 by a review of the aircraft maintenance records. | |
| 2 For aeroplanes with S/N 7305 through 7990, 8000 and subsequent - ADGs with part number 604-90800-1 (761339C), 604-90800-17 (761339D) or604-90800-19 (761339E) and with a S/N listed in Table 1 may not be installed on any aeroplane as a replacement spare, unless it is identified with the symbol“24-2” (refer Hamilton Sundstrand SB ERPS10AG-24-2) on the identification plate. |
