27-JA 181040 TITLE: FLYING CONTROLS - INSPECTION OF RUDDER AND ELEVATOR FLIGHT CONTROL CABLE TERMINALS FOR CORROSION.
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:

INDEPENDENT INSPECTION
WHENEVER ANY PART OF THE MAIN OR ASSOCIATED SYSTEM IS DISMANTLED,
ADJUSTED, REPAIRED OR RENEWED, THAT PART OF THE SYSTEM WHICH HAS
BEEN DISTURBED SHALL BE SUBJECTED TO AN INDEPENDENT INSPECTION FOR
SECURITY OF LOCKING DEVICES, FULL AND FREE MOVEMENT, DIRECTION AND TENSION CHECKS. THIS WORK MUST BE DONE IN ACCORDANCE WITH THE ACCEPTABLE MEANS OF COMPLIANCE M.A. 402 (a) TO EASA PART M, OR TO AN EQUIVALENT NATIONAL STANDARD.
WARNING: MAKE SURE THE AIRCRAFT AND THE AIRCRAFT SYSTEMS ARE MADE
SAFE AS DETAILED IN THE APPLICABLE CHAPTERS OF THE AIRCRAFT MAINTENANCE MANUAL.
WARNING: THE MINIMUM CLEARANCE BETWEEN MOVING AND STRUCTURAL PARTS MUST BE 0.2 IN (5.1 MM) UNLESS OTHERWISE STATED.
CAUTION: TO AVOID DAMAGE, MAKE SURE BEFORE MOVING CONTROLS THAT
CONTROL RUNS AND CONTROL SURFACES ARE FREE FROM OBSTRUCTION.
CAUTION: IF AN ELECTRICAL CONNECTION OR CONNECTOR IS DISMANTLED,
ASSEMBLED OR REPLACED, DO A CONTINUITY CHECK AND, IF
APPLICABLE, A SCREEN BONDING CHECK BEFORE THE ASSEMBLY IS CONNECTED TO EQUIPMENT.
NOTE: Abbreviations are used in the Accomplishment Instructions as follows:
- AMM Aircraft Maintenance Manual.
- assy. assembly.
- DVI Detailed Visual Inspection.
- i.a.w. in accordance with.
A. Preparation
(1) Refer to AMM Chapter 24-00-00. Remove electrical power from the aircraft.
(2) Display warning notices in the flight compartment 'DO NOT APPLY POWER TO THE AIRCRAFT' and 'DO NOT OPERATE THE FLIGHT CONTROLS.
(3) Remove equipment, furnishings and floor panels necessary to gain access to cable assemblies that require to be inspected.
B. Inspection Part 1 - DVI of Primary Rudder Flight Control Circuit Cable Terminals
(1) With reference to AMM Chapters 25 and 27, gain access to rudder flight control circuit cable assemblies:
