COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Lancair Series Aeroplanes
AD/LANCAIR/1 Canopy Latching 2/95 DM
Applicability: All models
Requirement: 1. Inspect the canopy internal latching system to ensure that:
- the latching is readily accessible and requires no exceptional agility or skill in its operation when used in an emergency;
b. the method of opening is simple and obvious;
c. it is arranged and marked for easy operation, even in darkness; and
d. any external auxiliary locking device used to secure the aircraft is able to be overridden by the normal internal opening means.
2. If the latching system does not fulfil all of the criteria of Paragraph 1, modify in accordance with a scheme acceptable to the Authority.
Note: Notwithstanding any Airworthiness Authority issued to a builder, this inspection is to be carried out and certified by a LAME licensed in the appropriate category; i.e. Airframe Group 1.
Compliance: Prior to:
- further flight after 7 December 1994, and thereafter at each inspection for Maintenance Release issue, and
b. the issue of a Certificate of Airworthiness.
Background: A report has been received that indicates that difficulty in operating the internal latching system of the canopy may prevent both normal and emergency egress.
Overview
The Civil Aviation Regulations 1998, which were enacted by the Australian Government, establish a comprehensive framework for ensuring the safety and airworthiness of aircraft operating within Australia. A specific legislative instrument, F2006B11084, under PART 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, addresses issues related to the Lancair series aeroplanes, particularly concerning the canopy latching system. This directive was introduced to address the problem of potential difficulties in operating the canopy latching system, which could impede both normal and emergency egress from the aircraft. The policy objective is to mandate rigorous inspection and, if necessary, modification of the canopy latching system to ensure it meets the specified criteria for accessibility, simplicity, and operational clarity. This is to be overseen by a Licensed Aircraft Maintenance Engineer (LAME) certified in the appropriate category.
This legislative instrument underscores the importance of maintaining high safety standards in civil aviation by specifically targeting the functionality of the canopy latching system in Lancair series aeroplanes. By requiring inspections and modifications to the latching system to ensure it is easily operable in both normal and emergency conditions, the regulation aims to mitigate risks associated with inaccessibility or complexity in the operation of the canopy, thus contributing to overall flight safety.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Schedule of Airworthiness Directives, mandates the inspection and modification of the canopy latching system for all models of Lancair series aeroplanes. This legislation applies to any aircraft within the specified category and mandates that the inspection and necessary modifications be conducted by a Licensed Aircraft Maintenance Engineer (LAME) licensed in the appropriate category, specifically Airframe Group 1. The inspection and compliance requirements are triggered before further flight after 7 December 1994 and at each inspection for Maintenance Release issue and the issuance of a Certificate of Airworthiness. The purpose of this regulation is to ensure the latching system is readily accessible, requires no exceptional skill to operate in an emergency, is simple and obvious in its operation, and can be easily operated even in darkness, with any external locking devices capable of being overridden by the normal internal opening means. If the existing latching system does not meet these criteria, it must be modified according to a scheme acceptable to the Civil Aviation Safety Authority.
Key Provisions
The key provisions of the Civil Aviation Regulations 1998, specifically Part 39, require inspections and modifications to the canopy latching systems of Lancair Series Aeroplanes. Section 105 mandates that all models of Lancair Series Aeroplanes must have their canopy internal latching systems inspected to ensure they meet specific criteria. These include being readily accessible, simple and obvious in operation, arranged and marked for easy operation even in darkness, and capable of being overridden by the normal internal opening means if an external auxiliary locking device is used (Section 105(1)). If the current system does not meet these criteria, modifications must be made according to a scheme acceptable to the Civil Aviation Safety Authority (CASA) (Section 105(2)). The inspection and certification must be carried out by a Licensed Aircraft Maintenance Engineer (LAME) licensed in the appropriate category, specifically Airframe Group 1 (Section 105(3)).
The obligations imposed by these regulations are that aircraft owners or operators must ensure that their Lancair Series Aeroplanes comply with the specified requirements. This includes conducting the necessary inspections and making any required modifications to the canopy latching system. The inspections must occur before further flight after 7 December 1994 and at each inspection for Maintenance Release issue or the issue of a Certificate of Airworthiness. The modifications must be documented and approved by CASA to ensure the safety of the aircraft and its occupants.
Failure to comply with these regulations can lead to various consequences. CASA has the authority to take enforcement actions against non-compliance, which may include fines, penalties, or other legal actions. While the specific penalties are not outlined in the provided text, non-compliance can potentially lead to serious safety risks, including difficulties in emergency egress, which could result in severe injury or loss of life. Ensuring adherence to the regulations is crucial for maintaining the airworthiness and safety of Lancair Series Aeroplanes.
