Overview

The Civil Aviation Safety Regulations 1998 (CASR) were enacted to ensure the safety and airworthiness of aircraft operating within Australia. The regulations are administered by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Act 1988, and they provide the framework for enforcing aviation safety standards. The specific legislative instrument referenced here, F2006B07383, pertains to Airworthiness Directives issued under the authority of CASA. This particular Airworthiness Directive (AD/TBM 700/34) was introduced to address a safety issue identified in the Aerospatiale (Socata) TBM 700 Series aeroplanes, specifically concerning the locking mechanism of the pilot and front passenger seats. The directive was issued following an incident where a pilot seat unlocked during a test flight due to potential interference between a side upholstery panel and the seat housing, which could result in the seat not locking properly. The objective of this directive is to ensure that the specified maintenance action is taken to rectify this unsafe condition, thereby maintaining the airworthiness of the affected aircraft.

Scope and Application

The Civil Aviation Safety Regulations 1998, as detailed in the specified legislative instrument, pertain to aircraft and aeronautical products within the jurisdiction of the Australian Commonwealth. This particular Airworthiness Directive (AD) targets the Aerospatiale (Socata) TBM 700 Series Aeroplanes, specifically models TBM 700 C2 and TBM 700 C1 aircraft equipped with option OPT 70 01-029 “Provision for T700C2.” The directive mandates corrective actions to address an identified unsafe condition concerning the pilot and front passenger seats. The directive is issued under subregulation 39.1 (1) of the Civil Aviation Safety Regulations 1998 by a delegate of the Civil Aviation Safety Authority (CASA) and requires compliance with the specific instructions provided in EADS Socata Alert Service Bulletin No. 70-121. The directive applies to all aircraft of the specified models and must be complied with before the next flight after 2 June 2004 and during each subsequent seat adjustment post this date. This AD was published in the Commonwealth of Australia Gazette on 2 June 2004.

Key Provisions

The Civil Aviation Safety Regulations 1998 (CASR), specifically Part 39 - 105, contains detailed provisions for ensuring the safety of aircraft and aeronautical products. The relevant section here, AD/TBM 700/34, pertains to the Aerospatiale (Socata) TBM 700 Series Aeroplanes, focusing on the pilot seat and front passenger seat. The directive mandates actions necessary to correct an identified unsafe condition, namely the risk of seat unlocking during flight due to interference between a side upholstery panel and the seat housing. The AD applies to all TBM 700 C2 aircraft and TBM 700 C1 aircraft equipped with the option OPT 70 01-029 "Provision for T700C2." This means that the corrective action must be undertaken on these specific aircraft models and configurations. The directive requires compliance with the Accomplishment Instructions detailed in EADS Socata Alert Service Bulletin No. 70-121, which provides the specific procedures to follow to mitigate the risk of seat unlocking. It is also noted that this directive aligns with DGAC Emergency AD UF-2004-069. The compliance requirements outlined in the AD are stringent and time-bound. Aircraft operators must ensure that the specified actions are completed before the next flight after 2 June 2004 and during each subsequent seat adjustment after this date. This means that the corrective measures must be implemented immediately upon the directive's effective date, which is 2 June 2004. Failure to adhere to these requirements could result in continued operation of the aircraft under unsafe conditions, potentially leading to significant safety risks during flight. Under the CASR, non-compliance with Airworthiness Directives can result in serious consequences. The regulations establish both civil and criminal penalties for breaches. Civil penalties may include fines up to a substantial amount, reflecting the seriousness of non-compliance with safety directives. Criminal penalties can include imprisonment, reflecting the potential severity of the consequences if such directives are ignored, leading to accidents or other safety incidents. Therefore, it is imperative for operators to follow these directives meticulously to avoid these penalties and ensure the continued airworthiness of their aircraft.
