Instructions For Continued Airworthiness (ICA’S)



          Instructions for Continued Airworthiness (ICA’s) have become a common term in aviation maintenance. ICA’s encompass Service Publications, Maintenance Manuals, Vendor Manuals referenced in the airplane maintenance manual, maintenance and inspection instructions provided by supplemental type certificate holders as well as the Cessna publications specifically titled “ICA” followed by the model number of the airplane for which they are applicable. It is the latter that many are not familiar with. These documents are a supplement to the airplane maintenance manual and provide the latest information when inspecting, troubleshooting or performing maintenance on the airplanes to which they are applicable.
Cessna has published various ICA’s for all of the current production models of aircraft. The data in these ICA’s covers information on maintaining and inspecting equipment or systems incorporated in production that have not been incorporated in the maintenance manual. It should be noted that this information may be incorporated in the maintenance manual in the future and when incorporated the maintenance manual will take precedence.
ICA’s are available on the Cessview IIi DVD or CD-ROM digital publications or they can be accessed at cessnasupport.com through the customer access portal.
            Where are the ICA’s in Cessna Publications? The applicable Model ICA’s are listed in the Cessview IIi maintenance manual set for the “Single Engine Restart” aircraft. The ICA’s can also be found on the www.cessnasupport.com publication search page. Remember to use the “percent” % wildcard when using this search engine. It will make the search much more productive when you don’t know the publication number.

Appendix H to Part 25—Instructions for Continued Airworthiness
H25.1General.
(a) This appendix specifies requirements for preparation of Instructions for Continued Airworthiness as required by §§ 25.1529, 25.1729, and applicable provisions of parts 21 and 26 of this chapter.
(b) The Instructions for Continued Airworthiness for each airplane must include the Instructions for Continued Airworthiness for each engine and propeller (hereinafter designated “products”), for each appliance required by this chapter, and any required information relating to the interface of those appliances and products with the airplane. If Instructions for Continued Airworthiness are not supplied by the manufacturer of an appliance or product installed in the airplane, the Instructions for Continued Airworthiness for the airplane must include the information essential to the continued airworthiness of the airplane.

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
