AD/BEECH 90/28 - Flap Bracket - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, are designed to ensure the safety and regulation of civil aviation within the country. One specific legislative instrument under this Act is F2006B04219, which introduces an Airworthiness Directive (AD) for Beechcraft 90 and 65-90 (King Air) Series Aeroplanes, addressing the need for regular inspections of the flap actuator brackets and adjacent structures to prevent potential failures. This AD was introduced to fill the gap in safety protocols by requiring inspections after 1000 hours of service and subsequent periodic checks to ensure ongoing airworthiness, thereby enhancing overall aviation safety. The policy objective is to minimise risks associated with structural failures in these aircraft models. The AD/BEECH 90/28 was issued by the Civil Aviation Safety Authority (CASA) under the authority of the Civil Aviation Act 1988, aiming to maintain and improve the safety standards in civil aviation. The directive mandates inspections of the flap actuator brackets on Beechcraft 90 and 65-90 aeroplanes to detect any cracks or signs of distress, ensuring that these aircraft remain airworthy and safe for operation. This regulatory approach is intended to proactively address potential safety hazards, thereby protecting both the crew and passengers aboard these aircraft.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 - 105, specifically address the safety and airworthiness of aircraft through Airworthiness Directives. One such directive, AD/BEECH 90/28, pertains to the inspection of flap brackets on Beechcraft 90 and 65-90 (King Air) series aeroplanes. This directive applies to all models of these aircraft that have accumulated 1000 or more hours in service. The requirement is for operators to inspect the flap actuator brackets and adjacent structures on both the right and left flaps for any cracks or signs of distress. Compliance must be achieved within 100 hours of time in service after the directive's effective date of 31 August 1972, and subsequently, inspections must be conducted at intervals not exceeding 300 hours of time in service. The regulations are enforced by the Civil Aviation Safety Authority and have a national reach throughout Australia. Subordinate instruments may further extend or clarify the requirements of the directive as necessary.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39, specifically in Section 105, mandate certain safety directives for aircraft, including the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes. Section AD/BEECH 90/28, issued on 8/72, is an Airworthiness Directive that requires the inspection of the flap actuator bracket and adjacent structure on the right-hand (RH) and left-hand (LH) flaps for any signs of cracks or distress. This directive applies to all models of the King Air series aeroplanes that have accumulated 1000 or more hours of time in service. The primary requirement under this section is that an inspection must be conducted within 100 hours of time in service following the date of the directive, which was 31 August 1972. Thereafter, the inspections must be repeated at intervals not exceeding 300 hours of time in service. This regular inspection regime is crucial to ensure the continued airworthiness of the aircraft, maintaining safety standards and preventing potential structural failures that could compromise flight safety. Compliance with these regulations imposes specific obligations on the operators of the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes. Operators must ensure that the inspections are carried out by qualified personnel and that the findings are documented appropriately. The directive necessitates that any discovered cracks or signs of distress are addressed promptly to maintain the aircraft's airworthiness. Additionally, operators must keep detailed records of all inspections performed, including the date, the findings, and any remedial actions taken. Failure to comply with these airworthiness directives can result in serious consequences. The Civil Aviation Regulations 1998 outline potential offences, penalties, and consequences for non-compliance. Under these regulations, non-compliance with airworthiness directives can lead to criminal charges, which may result in fines or imprisonment. Specifically, the maximum penalty for contravening these provisions can include fines up to a certain amount and imprisonment for a specified duration, depending on the severity of the breach and its impact on aviation safety. Additionally, civil penalties may apply, further enforcing the importance of adhering to the stipulated inspection requirements.
