CIRRUS AIRPLANE MAINTENANCE MANUAL MODEL SR22

AUXILIARY STRUCTURE

1. DESCRIPTION The leading edge of the wing is manufactured from composite materials. This airplane has a one-piece wing with individual wing tips. The wing tips are manufactured from composite materials. Each strobe light module is secured inside the corresponding wing tip. Stall strips are installed along the inboard leading edge of wing cuffs on both wings and promote a more gradual stall, prolonging aileron effectivity under stall conditions. Serials 2438 & subs: A white recognition light is installed on the leading edge of each wing tip.

2. MAINTENANCE PRACTICES A. Wing Tip - Serials 0002 thru 2437 (See Figure 57-201) (1) Removal - Wing Tip (a) Set BAT 1, BAT 2, and AVIONICS switches to OFF positions. (b) Pull NAV LIGHTS and STROBE LIGHTS circuit breakers.

Note: Place a pad between wing tip and top of wing to avoid damaging paint.

(c) Remove screws securing wing tip to wing and slide wing tip outboard to remove. Carefully flip wing tip upside down and rest wing tip on top of wing. (d) Remove clamp securing braided ground strap to wing wire harness conduit. (e) Disconnect wire harnesses. 1 Remove cable ties securing braided ground strap to wing wire harness. 2 Disconnect navigation light connector. 3 Disconnect power connector from strobe light module. 4 Serials 0002 thru 0497: Remove strobe light module mounting screw securing wire harness terminal rings. 5 Serials 0498 & subs: Disconnect terminal ring connector and remove cable tie securing wires together. (f) Remove wing tip from airplane. (2) Installation - Wing Tip (a) Connect wire harnesses. 1 Connect power connector to strobe light module. 2 Serials 0002 thru 0497: Position terminal ring between strobe light module and shear web and secure with screw. 3 Serials 0498 & subs: Connect terminal ring connector and install cable tie securing wires together. 4 Connect navigation light connector. (b) Wrap braided ground cable around wire harness and secure with cable ties. (c) Burnish wing conduit to ensure proper contact between braided ground strap and conduit. (d) Position braided ground strap to wing conduit and secure with clamp. (e) Verify resistance from anti-collision strobe light assembly to airplane ground is less than 4 ohms. If resistance is greater than 4 ohms, remove braided ground strap and repeat con- duit burnishing. (f) Position wing tip to wing and ensure wing tip shear pin fully engages receiving hole on wing. (g) Install screws securing wing tip to wing. (h) Reset NAV LIGHTS and STROBE LIGHTS circuit breakers. (i) Verify proper anti-collision strobe light operation.

(d) Disconnect wire harnesses. 1 Disconnect recognition light connector. 2 Disconnect navigation light connector. 3 Disconnect power connector from strobe light module. 4 Disconnect terminal ring connector and remove cable tie securing wires together. (e) Remove wing tip from airplane. (2) Installation - Wing Tip (a) Connect wire harnesses. 1 Connect power connector to strobe light module. 2 Connect terminal ring connector and install cable tie securing wires together. 3 Connect navigation light connector. 4 Connect recognition light connector. (b) Position wing tip to wing and ensure wing tip fully engages mounting clips on wing. (c) Install screws securing wing tip to wing. (d) Reset NAV LIGHTS and STROBE LIGHTS circuit breakers. (e) Verify proper anti-collision strobe light operation. (f) Verify proper recognition light operation.
