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 -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...
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....
