D2T-T2 R6 Flight testing of aircraft

 D2T-T2 R6   10th January 2022 Flight testing of aircraft for which a Certificate of Airworthiness has previously been issued.

Changes are as followes:

3. CIRCUMSTANCES NECESSITATING FLIGHT TESTING: 

3.1 An aircraft shall be flight tested under the circumstances mentioned below: 

(a) Subsequent to a major inspection schedule/ as specified by the manufacturer in case of scheduled airlines. 

Note: Scheduled airlines, which have a system (vide para 7 of this CAR) of meticulous flight monitoring of each revenue flight, for the guidance of their operating crew and also have a flight performance evaluation cell in their engineering organisation acceptable to DGCA, need not subject individual aircraft to test flight for the purpose of issue/ extension of ARC except under the circumstances detailed belowin sub-paras (c) to (e). The Continuing Airworthiness Manager should furnish a certificate during every issue/extension of ARC certifying that the aircraft performance has been continuously monitored and the performance is satisfactory. The procedures to be adopted by the performance evaluation cell shall be documented in the organization approved CAME. 

(b) At the time of issue/ extension of ARC for aircraft other than those operated by a scheduled airline in the following cases: 

i) The ARC has expired; or 

ii) The aircraft has not flown in the preceding 15 days prior to the expiry date of ARC. 

 (c) Subsequent to maintenance, repair, or modification which affects operational or flight characteristics of the aircraft.

(d) For the purpose of evaluation in respect of fuel consumption, engine power, performance of radio/ radar/ navigational equipment or instruments, whenever these cannot be satisfactorily checked on ground. 

 (e) Subsequent to change of engine. 

 (i) On a twin engined aircraft, a test flight after an engine change may not be carried out provided satisfactory engine ground testing procedure subsequent to an engine change and acceptable to Director General of Civil Aviation is evolved prior to availing of this relaxation. However, if both the engines are changed a Test Flight is necessary.

Cessna 152 Magneto Check

MAGNETO CHECK. NEVER ADVANCE TIMING BEYOND SPECIFICATIONS IN ORDER TO REDUCE RPM DROP. Too much importance is being attached to RPM drop in single ignition. RPM drop on single ignition is a natural characteristic of dual ignition design. The purpose of the following magneto check is to determine that all cylinders are firing. If all cylinders are not firing, the engine will run extremely rough and cause for investigation will be quite apparent. The amount of RPM drop is not necessarily significant and will be influenced by ambient air temperature, humidity, airport altitude, etc. In fact, absence of RPM drop should be cause for suspicion that the magneto timing has been bumped up and is set in advance of the setting specified. Magneto checks should be performed on a comparative basis between individual right and left magneto performance. a. Start and run engine until the oil and cylinder head temperatures are in normal operating ranges. b. Advance engine speed to 1700 RPM. c. Tu...

Brake System Cessna 172

                             BRAKE SYSTEM -MAINTENANCE PRACTICES              1. Description and Operation A. The hydraulic brake system is comprised of two master cylinders, located immediately forward of the  pilot’s rudder pedals, brake lines and hoses, and single-disc, floating cylinder brake assemblies located at  each main landing gear wheel. B. The parking brake system is comprised of a pull-type handle and mechanical connections which are  linked to the rudder pedal assembly. Pulling aft on the brake handle applies mechanical pressure to the  rudder pedals, activating the brakes and locks the handle in place. Turning the handle 90 degrees will  release the parking brake and allow for normal operation through the rudder pedals. C. Brake operation is accomplished by pushing on the upper part of each rudder pedal. This motion i...

McCauley Propeller Installation fixed pitch

Image
Propeller Installation for all fixed pitch propellers (except 1A162 model propellers).                   WARNING: MAKE SURE THE MAGNETO IS GROUNDED BEFORE INSTALLING  THE PROPELLER OR CONNECTING EXTERNAL POWER.                NOTE: McCauley recommends that propeller mounting nuts (if applicable) be replaced at each  propeller installation, whenever possible. However, nuts may be reused providing the threads are in good condition and the locking material prevents turning of the nut on the  stud by hand. Propeller mounting bolts must be magnetic particle inspected in accordance  with ASTM E-1444 or replaced whenever the propeller is removed from the engine.                NOTE: The aircraft maintenance manual or STC installation instructions should always be  consulted for any specialized procedures applicable to a specific aircraft....
