Internal concession register shall be established and made available, to DGCA for scrutiny.  
 Internal audit plan ( March to June) - can revised upto 30th September.
Audits to subcontractors  can be postponned upto 30th September.
 Canges to the organisation in this period to be reportted to DGCA. 
Extension of calibration due date may be extended  in accordance with the following conditions: 
 
a) when the normal calibration period is ≤ 12 months, the extension of the calibration can  be up to a maximum of 10% of the normal calibration, and; 
b) when the calibration period is > 12 months, the extension of the calibration can be 10% of the normal calibration period up to a maximum of 3 months, and; 
 c) the AMO has identified the risk associated to the use of the tool for the specific task in relation to continuing airworthiness of the aircraft, product or component as “low”, and; 
d) the tool is inspected before use and no damage or corrosion is identified, and; 
e) the tool was used at least once within the 3 months preceding the calibration due date, and;
 f) no deficiency with the use of this tool has been reported since the last calibration, and; 
 g) the last two calibration results are not showing any possible issue (e.g.: drift in the value, value very closed to the acceptable limit, etc.) that can endanger the maintenance. 
 Tools and equipment periodical maintenance and facilities checks  - may extend the maintenance/ service due date in accordance with the following conditions: 
 
a) the AMO has identified the risk associated to the use of the tool, equipment or the facilities for the specific task in regard to continuing airworthiness of the aircraft, product or component as “low”, and; 
b) the last maintenance result is not showing possible issue that can endanger the maintenance, and; 
c) no deficiency with the use of this tool, equipment of facilities has been reported since the last maintenance, and; 
d) the tool, equipment or facility is inspected before every use and no damage, corrosion or deterioration has been identified.

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 is  mechanically transmitted to the respective brake master cylinder, and through fluid-carrying lines out to  the brake assembly where fluid pressure

McCauley Propeller Installation fixed pitch

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. Various spinner arrangements not manufactured by McCauley may be used which require additional procedures. (1) Make sure the mating surfaces of t
