INSPECTION 1. PLANNING INFORMATION Effectivity All Jetstream Series 3100 and 3200 aircraft. B. Reason Following reports of control cable terminal failure on a range of civil aircraft it was found that the same specification of cable terminals were used on the Jetstream 3100 and 3200 Series aircraft. On the Jetstream Series aircraft the terminals are used in the rudder and elevator primary flight control cable circuits. C. Description This Service Bulletin (SB) introduces a repetitive inspection to check all threaded turnbuckle type control cable end fittings in the rudder and elevator primary flight control cable circuits for signs of corrosion, pitting or cracking. This SB is in two parts: Part 1 describes the detailed visual inspection of the rudder primary flight control cable terminals. Part 2 describes the detailed visual inspection of the elevator primary flight control cable terminals. D. Manpower 4 man-hours (Inspection only - excludes time for gaining access to the affected areas and restoration of equipment/furnishings after inspection). Mechanical skills are necessary. E. Material - Cost and Availability The material cost and availability are advised on request from: Saywell International Limited, Aviation Centre, Downlands Business Park, Worthing, ORIGINAL ISSUE: JAN 17/19 27-JA181040 PAGE 1 OF 12 ### Page 4 (OCR) BRITISH AEROSPACE JETSTREAM SERIES 3100 & 3200 SERVICE BULLETIN West Sussex, BN14 9LA, England E-mail: sales@saywell.co.uk Tel: +44(0)1903 704900 Fax: +44(0) 1903 704901 F.

Approval The technical content of this SB is to be the subject of EASA Airworthiness Directive (AD) consultation. For all cables with over 15 years time in service, the initial inspections detailed in para.2.A of this SB must be carried out within 12 months from the original issue date of this SB. For those cables that have less than 15 years time in service, they must be inspected in accordance with para.2.A of this SB within a period of 12 months on reaching 15 years time in service. NOTE: If no evidence of cable time in service is available from the aircraft records, it should be treated as having over 15 years time in service. The inspections have to be repeated thereafter at intervals of no more than 24 months.
