AD/CESSNA 303/8 Slick Pressurized Magnetos 4/89
Applicability: All Cessna T303 aircraft fitted with Slick model 6220 or 6224 pressurized magnetos.
Requirement: 1. Fabricate and install on the instrument panel in clear view of the pilot, a clearly legible placard with the following wording;
PRIOR TO EACH FLIGHT, CONDUCT MAGNETO CHECKS IN ACCORDANCE WITH AFM AMENDMENT INTRODUCED BY AD/CESSNA 303/9.
2. Action in accordance with Slick SB 1-88 Paragraph III, 100 hour inspection.
Note: AD/CESSNA 303/9, FAA AD 88-25-04 and Teledyne Continental Service Bulletin M88-14 also refer.
Compliance: 1. Within 100 hours TIS after 20 April 1989 and concurrent with AD/CESSNA 303/9.
2.a. Within 100 hours TIS after 20 April 1989, and then at intervals not exceeding 100 hours TIS following this initial inspection.
2.b. Whenever the magnetos fail the AFM check introduced by AD/CESSNA 303/9.
Background: Slick have advised that the magneto installations on the applicable aircraft are susceptible to moisture contamination which could result in engine stoppage.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, aim to ensure the safe operation of aircraft within Australian airspace. Specifically, Part 39 - 105 of the Regulations includes the Civil Aviation Safety Authority's schedule of airworthiness directives to address issues affecting the safety of particular aircraft models. The directive AD/CESSNA 303/8 pertains to Cessna T303 series aeroplanes fitted with Slick model 6220 or 6224 pressurized magnetos, targeting the problem of moisture contamination which can lead to engine stoppage. This directive mandates the installation of a placard reminding pilots to conduct magneto checks prior to each flight and adhere to the requirements specified in Slick SB 1-88 Paragraph III, 100-hour inspection. The policy objective is to enhance flight safety by preventing engine stoppages caused by moisture contamination in the magnetos. Compliance with this directive is required within 100 hours of total flight time after 20 April 1989 and must be maintained at intervals not exceeding 100 hours thereafter or whenever the magnetos fail the Airframe Manufacturer's check introduced by AD/CESSNA 303/9.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, address airworthiness directives concerning the maintenance and operation of civil aircraft, including the Cessna T303 Series Aeroplanes. This legislative instrument applies to all Cessna T303 aircraft equipped with Slick model 6220 or 6224 pressurized magnetos. The regulations mandate that a placard must be installed on the instrument panel to remind pilots to conduct magneto checks prior to each flight in accordance with the Airworthiness Flight Manual (AFM) amendment introduced by AD/CESSNA 303/9. Additionally, the directive requires actions in line with Slick Service Bulletin 1-88 Paragraph III for a 100-hour inspection. Compliance with these regulations is crucial, with the initial inspection required within 100 hours of Time in Service (TIS) after 20 April 1989, concurrent with AD/CESSNA 303/9. Subsequent inspections must occur at intervals not exceeding 100 hours TIS, and any time the magnetos fail the AFM check introduced by AD/CESSNA 303/9. The directive is intended to mitigate risks of engine stoppage due to moisture contamination in the magneto installations.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the application of airworthiness directives for certain aircraft types. One such directive, AD/CESSNA 303/8, pertains to all Cessna T303 aircraft equipped with Slick model 6220 or 6224 pressurized magnetos. The directive requires that a clearly legible placard be fabricated and installed on the instrument panel, visible to the pilot, stating that magneto checks must be conducted in accordance with the Airframe Manual (AFM) amendment introduced by AD/CESSNA 303/9 prior to each flight. Additionally, the directive mandates actions as outlined in Slick Service Bulletin 1-88, Paragraph III, particularly a 100-hour inspection of the magnetos.
The regulations impose several obligations on the parties involved. Firstly, operators of the affected Cessna T303 aircraft must ensure that the required placard is installed within 100 hours of Time in Service (TIS) after 20 April 1989 and must conduct the initial 100-hour inspection in accordance with the directive. Furthermore, subsequent inspections must be carried out at intervals not exceeding 100 hours TIS following the initial inspection. These inspections are crucial to prevent potential engine stoppages due to moisture contamination in the magneto installations.
Non-compliance with the airworthiness directive can result in significant legal consequences. While specific civil or criminal penalties are not detailed in the legislative instrument, failure to adhere to the prescribed inspections and placard installation could lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Such actions might include the grounding of the aircraft until the required checks and installations are completed, and could potentially lead to further administrative or legal penalties if the non-compliance is deemed to have endangered safety. Operators must, therefore, ensure strict adherence to the timelines and requirements set forth in AD/CESSNA 303/8 to avoid these consequences.
