Note 1: For the purposes of this Directive, an approved equivalent part number is defined as P/N approved under FAA Parts Manufacturing Approval or a CASA Australian Parts Manufacturing Approval.
2. If P/N 77041 (or an approved equivalent P/N) oil pressure switch is installed replace this switch with a P/N 83278 (or an approved equivalent P/N) oil pressure switch in accordance with SB00-79-01.
3. Oil pressure switch P/N 77041 (or an approved equivalent P/N) may not be installed on any aeroplane.
Note 2: FAA AD 2000-04-01 Amdt 39-11583 refers.
Compliance: For Requirement 1 - Within the next 25 hours time in service from the effective date of this Directive.

COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
This Airworthiness Directive becomes effective on 8 March 2000.
Background: This Directive results from reports received by the FAA of failures of oil pressure switch diaphragms. These failures could result in loss of engine oil and subsequent partial or complete loss of engine power. The Directive requires replacement of the defective switches.
Eugene Paul Holzapfel
Delegate of the Civil Aviation Safety Authority 2 March 2000
The above AD is notified in the Commonwealth of Australia Gazette on 8 March 2000.
Overview
The Civil Aviation Regulations 1998, amended by the Airworthiness Directive AD/CESSNA 206/51, was enacted to address the safety concerns associated with oil pressure switch failures in specific Cessna 206H and T206H model aeroplanes. This directive was introduced by the Civil Aviation Safety Authority (CASA) under subregulation 39.1 (1) of CAR 1998. The policy objective is to ensure the safety of air travel by mandating corrective actions for identified unsafe conditions. The directive became effective on 8 March 2000, requiring inspection and replacement of specific oil pressure switches to prevent potential engine failure due to loss of oil pressure, thereby maintaining the airworthiness of the affected aircraft.
Scope and Application
The Airworthiness Directive (AD) issued under the Civil Aviation Regulations 1998 applies specifically to the Cessna 206H and T206H model aeroplanes with serial numbers falling within certain ranges. This legislation is issued by the Civil Aviation Safety Authority (CASA) delegate, representing the Commonwealth of Australia, and mandates specific actions to address identified safety issues with the oil pressure switches of these aircraft models. The directive applies to the specified aircraft models and serial numbers, necessitating inspections and replacements of the oil pressure switches to ensure safety. The AD specifies that if an oil pressure switch of part number (P/N) 77041 or an approved equivalent is found, it must be replaced with P/N 83278 or an approved equivalent. The directive sets compliance timelines, requiring inspections within 25 hours time in service from the effective date, replacements before further flight, and a prohibition on the installation of P/N 77041 switches as of the effective date of the directive. The AD becomes effective on 8 March 2000 and is notified in the Commonwealth of Australia Gazette on the same date.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39, Section 105, establishes a schedule of Airworthiness Directives (AD) for civil aviation. One such AD is AD/CESSNA 206/51, which pertains to the oil pressure switch of Cessna 206 Series aeroplanes. This AD applies to specific serial numbers of Cessna 206H and T206H model aeroplanes, as detailed in the applicability section. The directive mandates that the oil pressure switch be inspected in accordance with Cessna Service Bulletin SB00-79-01 dated 31 January 2000 to determine if it is part number (P/N) 77041 (or an approved equivalent P/N) or P/N 83278 (or an approved equivalent P/N). If the switch is P/N 83278, no further action is required. If P/N 77041 (or an approved equivalent P/N) is installed, it must be replaced with P/N 83278 (or an approved equivalent P/N) as per SB00-79-01. Moreover, P/N 77041 (or an approved equivalent P/N) oil pressure switch must not be installed on any aeroplane.
The AD imposes obligations on the owners or operators of the specified aircraft models to comply with the requirements within specified timeframes. For Requirement 1, the inspection must be conducted within the next 25 hours of time in service from the effective date of the AD. Requirement 2 necessitates that the replacement of the defective switch must be completed before further flight. Requirement 3 must be adhered to immediately, meaning that P/N 77041 (or an approved equivalent P/N) oil pressure switch must not be installed on any aeroplane from the effective date of the AD onwards.
Non-compliance with this AD may result in serious safety risks, as the AD is designed to address potential failures of the oil pressure switch diaphragms, which could lead to loss of engine oil and subsequent partial or complete loss of engine power. While the AD itself does not explicitly state penalties, non-compliance with Civil Aviation Regulations 1998 could result in civil or criminal penalties. Under Section 24 of the Civil Aviation Act 1988, civil penalties can include fines up to $100,000 for corporations and $20,000 for individuals. In more severe cases, criminal penalties may apply, including imprisonment for up to two years for individuals and five years for corporations, along with fines up to $1,100,000 for corporations and $220,000 for individuals.
