AD/BEECH 95/31 - Interior Door Handles

Overview

The Civil Aviation Safety Authority (CASA) issued Airworthiness Directive AD/BEECH 95/31 in 1997 to address a safety concern identified with the Beechcraft 95 (Travelair) Series Aeroplanes. This directive mandates specific checks and, if necessary, corrections to the cabin side door and utility door handles to ensure they lock properly when rotated without the need to depress the lock release button. The directive responds to reports where these door handles opened unintentionally from the interior, posing a risk of distraction to the pilot and potential loss of control. The directive applies to models 95, B95, B95A, D95A, and E95 of the Beechcraft 95 Series and requires compliance within 50 hours’ time in service after 6 November 1997 or at the next door handle removal, whichever comes first. This measure aims to enhance the safety and reliability of these aircraft by preventing unintentional door openings.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority's schedule of airworthiness directives, applies to all Beechcraft 95 (Travelair) Series Aeroplanes, including models 95, B95, B95A, D95A, and E95 across all serial numbers. This legislation mandates a mandatory check on the cabin side door handle and the utility door handle from the interior of the aircraft to ensure proper locking. If the door handle opens the door without the lock release button being depressed, the directive requires the door handle to be corrected by removing and reinstalling it as per the Accomplishment Instructions section of Raytheon Service Bulletin 2693. Conversely, if the door handle locks properly and only unlocks when the lock release button is depressed, no further action is necessary. Compliance with this airworthiness directive must be met within 50 hours in service after 6 November 1997 or at the next door handle removal after this date, whichever occurs first, and subsequently whenever a utility or cabin interior door handle is removed. The directive aims to prevent unintentional opening of the cabin side door and the utility door from the interior of the aircraft, which could lead to loss of control due to pilot distraction.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates that the cabin side door handle and the utility door handle of Beechcraft 95 (Travelair) Series Aeroplanes, including models 95, B95, B95A, D95A, and E95 of all serial numbers, must be checked for proper locking (AD/BEECH 95/31). According to section 12/97, if the door handle opens the door when rotated without depressing the lock release button, corrective action must be taken. This involves removing the door handle and re-installing it so that the lock release button properly locks the door, following the Accomplishment Instruction section of Raytheon Service Bulletin 2693. If the door handle is already locked and will only unlock by depressing the lock release button, no further action is necessary. This directive ensures that the door handles function correctly, preventing unintentional opening from the interior, which could lead to loss of control due to pilot distraction. The obligations imposed by this directive require operators of the specified Beechcraft models to ensure that the door handles are checked and corrected if necessary, either within 50 hours of service time after 6 November 1997 or at the next door handle removal after that date, whichever comes first. This must also be done whenever a utility or cabin interior door handle is removed. The directive aims to maintain airworthiness by preventing issues that could compromise the safety of the aircraft. Failure to comply with the airworthiness directive can result in safety risks, as the unintentional opening of cabin or utility doors could lead to severe consequences. While specific penalties are not detailed within this text, non-compliance with Civil Aviation Regulations can generally lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions can include fines, legal proceedings, and potentially grounding the aircraft until compliance is achieved. The severity of the consequences would depend on the specific circumstances and the degree of non-compliance.
