SR22T Airplane Flight Manual (AFM) Temporary Change

Transcription

1 Cirrus Design TPOH Airplane Flight Manual (AFM) Temporary Change Information in this Temporary Change adds to, supersedes, or deletes information in the basic Pilot s Operating Handbook. Affected Publications: Filing Instructions: Purpose: Basic Airplane Flight Manuals: PN Original / Rev 1 / Reissue A (FAA Approved) PN AR Original / AR Original / AR Reissue A (FAA Approved on behalf of ANAC-DA of Argentina) PN E Original / E Rev 1 / E Rev 1 (FAA Approved on behalf of EASA) PN Original / Rev 1 / Rev 1 (FAA Approved on behalf of ANAC of Brazil) Insert the following changes adjacent to the first page of each affected POH Section, and insert this TPOH cover page adjacent to the last page of the List of Effective Pages. Retain until further notice. This POH Temporary Change updates information associated with the Brake System. TPOH was revised 19 May 2018 to add Affected Publications, expand SB2X effectivity, and update Nose Wheel PSI. Affected Sections: Section 7 - Systems Description Section 8 - Handling and Servicing Section 10 - Safety Information TPOH 15-16R1 1 of 8

3 Cirrus Design Section 7 - Systems Description Landing Gear Main Gear TPOH Each main gear wheel has a 15 x 6.00 x 6 tubeless tire installed. Nose Gear The tubeless nosewheel tire measures 5.00 x 5. Brake System The reservoir is serviced with MIL-PRF hydraulic fluid. A temperature sensor is mounted to each brake assembly and provides measured brake temperatures to the avionics system for caution and warning annunciation. TPOH 15-16R1 3 of 8

5 Cirrus Design TPOH Section 8 - Handling, Servicing, and Maintenance Servicing Landing Gear Servicing The main landing gear wheel assemblies use 15 x 6.00 x 6 tubeless tires. The nose wheel assembly uses a 5.00 x 5 tubeless tire. Brake Servicing Brake Replenishing The brake system is filled with MIL-PRF hydraulic brake fluid. To replenish brake fluid: 1. Chock tires and release parking brake. 2. Remove top engine cowling to gain access to hydraulic fluid reservoir. 3. Clean reservoir cap and area around cap before opening reservoir cap. 4. Remove cap and add MIL-PRF hydraulic fluid as necessary to fill reservoir. 5. Install cap, inspect area for leaks, and then install and secure engine cowling. TPOH 15-16R1 5 of 8

6 TPOH Tire Inflation To inflate tires: Cirrus Design 1. Remove inspection buttons on wheel pants to gain access to valve stems. It may be necessary to move airplane to get valve stem aligned with the access hole. 2. Remove valve stem cap and verify tire pressure with a dial-type tire pressure gage. Caution The LH and RH main wheel tire pressures must be within 20 psi of each other to ensure the load is evenly distributed between the main wheels. 3. Inflate nose tire to psi ( kpa) and main wheel tires to psi ( kpa). 4. Replace valve stem cap and inspection buttons. 6 of 8 TPOH 15-16R1

7 Cirrus Design Section 10 - Safety Information TPOH Taxiing, Steering, and Braking Practices Operating Practices Observe the following operating practices: Verify that the parking brake is completely disengaged before taxi. The rudder is effective for steering on the ground and should be used. Use only as much power (throttle) as is necessary to achieve forward movement. Keep in mind, any additional power added with the throttle will be absorbed in the brakes to maintain constant speed. Use rudder deflection and the minimum necessary inputs of differential braking to achieve directional control. Do not ride the brakes. Pilots should consciously remove pressure from the brakes while taxiing. Failure to do so results in excessive heat buildup, premature brake wear, and increased possibility of brake failure or fire. Avoid unnecessary high-speed taxiing. High-speed taxiing may result in excessive demands on the brakes, increased brake wear, and the possibility of brake failure or fire. Brakes have a large energy absorbing capacity; therefore, cooling time should be considered. Energy absorbed during a few seconds of deceleration can take several minutes to dissipate. Always allow adequate cooling time after brake use. Allow a cooling period following a high-energy braking event. High-energy braking can include an aborted takeoff or the equivalent energy required for a Maximum Gross Weight fullstop from 70 knots in less than 1000 feet. TPOH 15-16R1 7 of 8
