COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Cessna 210 Series Aeroplanes
AD/CESSNA 210/63 Slick Pressurized Magnetos - Flight Manual 4/89
Applicability: All Cessna T210L, T210M, T210N, and P210N series aircraft fitted with Slick Pressurized Magnetos model 6220 or 6224.
Requirement: 1. Revise the AFM by adding the following:
“BEFORE TAKEOFF"
Perform a magneto check of each engine at 1,700 RPM as follows: Move ignition switch first to R position and note RPM. Next, move switch back to BOTH, to clear the other set of plugs. Then, move switch to the L position, note RPM and return the switch to the BOTH position. RPM drop should not exceed 150 RPM on either magneto or show greater than 50 RPM differential between magnetos. If there is doubt concerning operation of the ignition system, RPM checks at higher engine speed will usually confirm whether a deficiency exists.
If the magneto check exceeds either of the above limits, both magnetos must be disassembled and inspected in accordance with requirement 2 of AD/CESSNA 210/62; an entry to this affect is to be made in the maintenance release by the pilot.
Note 1: The aforementioned amendment may be accomplished by inserting a copy of this AD into the relevant section of the AFM.
Note 2: AD/CESSNA 210/62, FAA AD-25-04, and Teledyne Continental Service Bulletin M88-14 also refer.
Compliance: Within 100 hours TIS after 20 April 1989 and concurrent with AD/CESSNA 210/62.
Background: The Before Take Off check introduced by this AD requires that any magneto which exceeds the limits specified in the check must be placed unserviceable in the maintenance release by the pilot and subsequently disassembled and inspected in accordance with AD/CESSNA 210/62.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, aims to ensure the safety of civil aviation within Australia's airspace. This legislation is overseen by the Civil Aviation Safety Authority (CASA) and is designed to maintain and improve aviation safety standards. One particular aspect of this regulation, AD/CESSNA 210/63, addresses the issue of ensuring the reliability and safety of the magneto systems on specific Cessna 210 series aircraft. The policy objective is to mandate rigorous pre-flight checks to prevent any potential failures during flight, thereby enhancing overall flight safety. This directive requires pilots to conduct a detailed magneto check before each takeoff, and if any discrepancies are found, the magnetos must be disassembled and inspected in accordance with another directive, AD/CESSNA 210/62. This ensures that any issues with the aircraft's ignition system are identified and rectified before flight, reducing the risk of in-flight failures.
Scope and Application
The Civil Aviation Regulations 1998, particularly PART 39 - 105, apply to all Cessna T210L, T210M, T210N, and P210N series aircraft equipped with Slick Pressurized Magnetos model 6220 or 6224. This regulation, outlined in AD/CESSNA 210/63, mandates specific operational checks and maintenance protocols to ensure the safety and airworthiness of these aircraft. The requirement entails performing a magneto check at 1,700 RPM before each takeoff, with specified RPM drop limits and differentials, to ascertain the functionality of the ignition system. Non-compliance with these checks necessitates disassembly and inspection of the magnetos, as per AD/CESSNA 210/62, and must be documented in the maintenance release by the pilot. The directive aims to maintain safety standards within the aviation sector, ensuring that any deficiencies in the ignition system are identified and rectified promptly. Compliance must be achieved within 100 hours of time in service after 20 April 1989, in conjunction with other referenced directives and service bulletins.
Key Provisions
The Civil Aviation Regulations 1998, particularly Part 39 - 105, establish critical safety directives concerning the airworthiness of specific aircraft models. Under this part, AD/CESSNA 210/63 mandates specific requirements for the Cessna T210L, T210M, T210N, and P210N series aircraft fitted with Slick Pressurized Magnetos model 6220 or 6224 (section 1). The main requirement of this directive is to revise the Aircraft Flight Manual (AFM) by adding a specific magneto check procedure to be performed before each takeoff. This check involves moving the ignition switch positions and monitoring the engine's RPM drop, ensuring that it does not exceed 150 RPM on either magneto or show a greater than 50 RPM differential between the two (section 2). If the RPM check reveals any doubts about the ignition system's operation, higher engine speed checks are recommended to confirm any deficiencies.
The obligations imposed by this directive are clear and precise. Aircraft operators must ensure that the AFM is updated to include the specified magneto check procedure. Pilots are required to perform this check before every takeoff, documenting any findings in the maintenance release. If the RPM check exceeds the specified limits, the magnetos must be disassembled and inspected according to the provisions of AD/CESSNA 210/62 (section 3). This inspection and documentation are crucial for maintaining the aircraft's airworthiness and ensuring compliance with the Civil Aviation Regulations.
Failure to comply with the requirements set forth in AD/CESSNA 210/63 can result in significant consequences. The regulations do not explicitly state the specific penalties or consequences for non-compliance in the provided text; however, general Civil Aviation Regulations often include provisions for fines, suspension of airworthiness certificates, and potential criminal charges for serious breaches. The penalties can vary depending on the severity and impact of the non-compliance, but they underscore the importance of adhering to these safety directives to protect both the aircraft and its occupants. Ensuring compliance is not only a legal obligation but also a critical safety measure to prevent potential in-flight issues.
