AD/PA-30/8 - Vmc Placard - Revision

Overview

The Civil Aviation Regulations 1998, specifically PART 39 - 105, addresses the scheduling of airworthiness directives through F2006B05682, a legislative instrument issued by the Commonwealth of Australia. This particular directive, AD/PA-30/8, targets Piper PA-30 & 39 (Twin Comanche) Series Aeroplanes, aiming to rectify discrepancies in the minimum single engine control speed placard. This was introduced to ensure compliance and enhance safety standards in civil aviation, specifically addressing the need for an accurate representation of the Vmc (Velocity, minimum control speed) on the aircraft placard. The policy objective here is to maintain airworthiness and ensure that pilots and owners are clearly informed about the minimum speed required for single engine control, which is a critical safety measure. The Civil Aviation Safety Authority mandates that the existing Vmc placard for Piper PA-30 models, excluding those incorporating Piper Kit 760 368 (reference SL 552), be revised to reflect "MINIMUM SINGLE ENGINE CONTROL SPEED 80 Kts. IAS". This change is intended to be performed and certified by the pilot or owner, with the stipulation that the lettering size on the new placard must not be smaller than that of the existing one. Compliance with this directive is required before any further flight after 26 November 1969, underscoring the importance of adhering to updated safety standards to prevent accidents and ensure the continued airworthiness of these aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the Piper PA-30 and 39 (Twin Comanche) series aeroplanes, excluding those that incorporate Piper Kit 760 368 (reference SL 552). This legislative instrument is pertinent to aircraft owners and pilots, mandating compliance with specific airworthiness directives to ensure safe operational standards. The requirement entails updating the Vmc placard on the affected aircraft to indicate "MINIMUM SINGLE ENGINE CONTROL SPEED 80 Kts. IAS". This directive is enforceable under Commonwealth jurisdiction, impacting all relevant aircraft operating within Australia. Compliance is mandatory before any further flight after 26 November 1969, and the task may be performed and certified by the pilot or owner, provided the minimum lettering size of the new placard meets or exceeds that of the existing one. This directive extends its reach through subordinate instruments that may further detail compliance and enforcement mechanisms.

Key Provisions

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, issue an airworthiness directive for Piper PA-30 and 39 (Twin Comanche) series aeroplanes. The directive, AD/PA-30/8, pertains to the revision of the Vmc (minimum single engine control speed) placard on models that do not incorporate Piper Kit 760 368 (reference SL 552). According to the directive (AD/PA-30/8), the existing Vmc placard must be altered or a new placard must be installed to display "MINIMUM SINGLE ENGINE CONTROL SPEED 80 Kts. IAS" (AD/PA-30/8). This revision applies to all affected aircraft after 26 November 1969, and it can be performed and certified by the pilot or owner, provided the new placard's lettering size is no smaller than the existing one (AD/PA-30/8). Under the Civil Aviation Regulations 1998, operators and owners of the specified Piper Twin Comanche series aeroplanes have the obligation to ensure compliance with the airworthiness directive AD/PA-30/8. This involves updating the Vmc placard to reflect the prescribed wording and lettering size before any further flights. The responsibility lies with the pilot or owner to perform the necessary modifications, ensuring that the new placard meets the specified standards. Compliance is mandatory and must be achieved before any subsequent flight after the directive's effective date of 26 November 1969. Failure to comply with the airworthiness directive AD/PA-30/8 can result in significant legal and operational consequences. Although the specific penalties are not detailed within the provided text, non-compliance with airworthiness directives under the Civil Aviation Regulations 1998 generally carries potential civil and criminal repercussions. Civil penalties can include fines, while criminal penalties might involve imprisonment, depending on the severity of the non-compliance and its impact on aviation safety. Operators and owners are thus required to take the directive seriously to avoid any legal ramifications and ensure continued airworthiness of their aircraft.
