Transcription

1 Page: 1 of 8 1. ATA Code: Effectivity: Serial number C0002 to C General: This service bulletin allows the installation of the Diamond Aircraft Flap Control Module Unit and microswitch tray. 4. Reason: The change was implemented due to the White Wire flap controller module no longer being available. 5. Compliance: Compliance with this Service Bulletin is optional. 6. Approval: Engineering data referenced or contained in this Service Bulletin is approved as part of the type design. 7. Labor: The labor hours required to install and setup flap actuator are 3.0 hours This estimate is for direct labor performed by a technician and it does not include setup, planning, familiarization, cure time, part fabrication or tool acquisition. 8. Material: Part Number Description Qty SB SB Flap Controller Module 1 MS Machine Screw Seal Retainer, Flap Actuator SB Rot, Actuator, Extension 1 XM-4MT-C3 Rod End Bearing 1 AN526C632R8 Screw 2 NAS1149FN632P Washer, Flat 2 AN3-3A Bolt, Hex 2 AN3-4A Bolt, Hex 3 NAS1149F0363P Washer, Flat Shield, Limit Switch, Flap Actuator MS Spring Pin 1 MS Spring Pin 1 MS21044N4 Nut,Hex,Self Locking 2 Material may be ordered as kit: DAC AMK0 Optionally a complete flap motor assembly can be ordered

2 Page: 2 of 8 Note: Serial numbers C0002 through C0144 may require Flap Controller Retrofit harness. The harness is required if the current installed flap controller has a circular connector. 9. Special Tools: N/A Flap Controller, Retrofit Harness References: DA20-C1 Aircraft Maintenance Manual, Document # DA201-C1 DA20-C1 Aircraft Flight Manual, Document # DA202-C1 11. General Instructions: Pull the Battery Circuit breaker located on the right side of the instrument panel Disconnect the aircraft battery as per AMM Chapter Remove instrument panel cover as per AMM Chapter Remove flap controller from instrument panel. Non-G500 Instrument Panel G500 Instrument Panel Plug flap controller connector on the instrument panel harness into the Diamond Aircraft flap controller (p/n: SB) and install into the same location as the previous controller using supplied hardware. NOTE: On Serial Number C0002 through C0144 if previously installed controller had circular connector, install retrofit harness (P/N )

3 Page: 3 of Remove flap actuator as per DA201-C1 AMM chapter If optional flap actuator assembly is ordered, steps 11.7 to not required. Proceed to step to complete installation Remove spring pin shown below and loosen hose clamps. Remove microswitch tray and rod assembly from flap motor. Loosen hose clamps Remove spring pin Assemble flap actuator as shown below with new supplied parts. Install and secure hardware with loctite 222. Existing clamps New Extension Rod ( SB) New Rod End (XM-4MT-C3) Existing motor New Microswitch tray ( )

4 Page: 4 of Position microswitch tray approximately 8mm from edge of actuator seal Install extension rod on to motor end, align pilot hole in extension rod with existing hole in motor end. Verify that extension rod has reached proper engagement. Open pilot hole on extension rod with a 1/8 drill bit as shown below. NOTE: Care should be taken not to bend switch plates at weld joints when drilling. Drill through motor end with 1/8 drill bit.

5 Page: 5 of Position rod end as shown below and drill threw extension rod hole and rod end with a 1/8 drill bit. NOTE: Care should be taken not to bend switch plates at weld joints when drilling. Drill through rod end with 1/8 drill bit Install spring pins into extension rod as shown below. Spring pin (MS171531) Spring pin (MS171528) NOTE: Care should be taken not to bend switch plates at weld joints when drilling.

6 Page: 6 of Install seal retainers using supplied hardware on both microswitch plates. Install and secure hardware with loctite 222. Bolt: AN3-3A Washer: NAS1149F0363P Bolt: AN526C632R8 Washer: NAS1149FN632P TESTING: Seal Retainer: (x2) Install flap actuator into aircraft as per DA201-C1 AMM chapter Use new (supplied) nuts Connect the aircraft battery as per ATA chapter of the DA20-C1 AMM Push in Battery circuit breaker and turn Electrical Master switch to ON Confirm that each flap position is within the range stated in the DA201-C1 AMM chapter If not, adjust the appropriate microswitch(es) accordingly While flaps are in T/O or Landing configuration apply a load on flap by pulling up to simulate wind drag force on flap. Observe to see if dual lights remain on. Adjust microswitches as required if dual lights observed Confirm on the aircraft s ammeter that the load drops when the flap actuator comes to rest after each cycle of the flap positions. If the load remains high check the following: If in the landing position adjust the LDG limit microswitch.

7 Page: 7 of If in the cruise position, adjust the microswitch tray. This may also require adjustment of the other switches after Install flap actuator shield (p/n: ) using supplied hardware (Bolt: AN3-4A, Washer: NAS1149F0363P). Install and secure hardware with loctite Loosen hose clamps and rotate microswitch tray so that the short side of cam can only be engaged by the plate with three microswitches. Tighten clamp Clean the work area and inspect for foreign objects Make a log book entry that this Service Bulletin has been incorporated. 12. Weight and Balance: Make the following adjustments to weight and balance: Items Removed Description White Wire Flap Controller Weight kg (lbs) 0.23 (0.51) Items Installed Description Diamond Aircraft Flap Controller Weight kg (lbs) (0.47)
