AD/BEECH 1900/31 - Landing Gear Emergency Hand Pump - Faulty Component Replacement

Overview

The Civil Aviation Regulations 1998, as amended, form part of the regulatory framework governing aviation safety in Australia. Enacted by the Australian Parliament, these regulations aim to ensure that civil aviation operations within the country meet internationally recognised safety standards. One such legislative instrument under these regulations is the Airworthiness Directive AD/BEECH 1900/31, which was introduced to address a specific safety concern associated with the Beechcraft 1900 Series aeroplanes. This directive mandates the replacement of faulty landing gear emergency hand pumps in Raytheon (Beechcraft) 1900D model aeroplanes to mitigate the risk of operational failure in emergency situations. The policy objective is to maintain and enhance the safety of civil aviation by ensuring that all applicable aircraft are fitted with reliable emergency equipment. Compliance with this directive is required within 25 hours of the effective date, which is 27 September 1999, as per the mandate set out by the Civil Aviation Safety Authority.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, addresses the safety requirements for the Beechcraft 1900 Series Aeroplanes through an Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority. This legislation applies to all Raytheon (Beechcraft) 1900D model airplanes, irrespective of their serial numbers. The directive mandates the replacement of any landing gear emergency hand pump, part number 101-388007-3, with a serial number within the range 2702 through 2833. Compliance is achieved by replacing the identified faulty components or ensuring the aircraft maintenance records confirm that the emergency hand pump serial number falls outside the specified defective range. The directive requires adherence within 25 hours of its effective date, which is 27 September 1999. The directive is grounded on information from the manufacturer indicating that certain emergency hand pumps have been machined incorrectly, thereby necessitating this corrective action to ensure safety in emergency situations.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39, contain specific directives regarding the airworthiness of aircraft, including the Beechcraft 1900 Series Aeroplanes. The regulation in question, AD/BEECH 1900/31, mandates the replacement of certain landing gear emergency hand pumps on all Raytheon (Beechcraft) 1900D model airplanes with serial numbers in the range of 2702 through 2833. This directive is crucial for ensuring the safety and airworthiness of these aircraft (AD/BEECH 1900/31). The requirement is straightforward: any affected hand pump must be replaced with a new one, and the defective components must be returned to the manufacturer for warranty action. Compliance can be demonstrated if the aircraft maintenance records show that the serial number of the installed emergency hand pump is outside the specified defective range (AD/BEECH 1900/31). The obligations imposed by this directive are clear and must be adhered to strictly. Operators of the affected aircraft must ensure that the landing gear emergency hand pumps are inspected and, if necessary, replaced within 25 hours of the directive's effective date, which is 27 September 1999. This inspection and replacement process must be documented in the aircraft maintenance records, providing a clear audit trail for compliance verification (AD/BEECH 1900/31). Additionally, the defective components must be sent back to the manufacturer, ensuring that the manufacturer is aware of the issue and can take appropriate warranty actions. Failure to comply with the provisions of AD/BEECH 1900/31 can result in serious consequences. While the specific penalties for non-compliance are not detailed in the directive, under the broader Civil Aviation Act 1988, non-compliance with airworthiness directives can lead to substantial fines and legal action. Furthermore, operating an aircraft that does not meet airworthiness standards poses significant safety risks, potentially leading to civil or criminal charges if an incident occurs due to the failure to comply with this directive. The seriousness of these potential consequences underscores the importance of adhering to the directive's requirements.
