COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Beechcraft 300 Series Aeroplanes
AD/BEECH 300/14 Landing Gear Emergency Hand Pump - Faulty
Component Replacement
Applicability: All Raytheon (Beechcraft) B300 model airplanes all serial numbers.
11/99
TX
Requirement: Replace any landing gear emergency hand pump, part number 101-388007-3, with a serial number in the range 2702 through 2833. Defective components are to be returned to the manufacturer for warranty action. Compliance can be shown if the aircraft maintenance records can identify positively that the serial number of the emergency hand pump fitted falls outside of the range of affected components.
Note: US FAA AD 99-18-15 Amdt 39-11281 dated 23 August 1999 refers.
Compliance: Within 25 hours time in service from the effective date of this Directive. This Airworthiness Directive becomes effective on 27 September 1999.
Background: Information from the manufacturer indicates that certain emergency hand pumps, fitted during manufacture or as replacement parts, within a specific range of serial numbers have been machined incorrectly and will not operate correctly in an emergency situation. This Directive introduces measures to identify and replace the defective components. All aircraft serial numbers are deemed applicable as any one of them may have had one of the defective components fitted during its operational life.
Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes an airworthiness directive addressing an identified issue with the landing gear emergency hand pump of Beechcraft 300 Series aeroplanes. This directive, AD/BEECH 300/14, was enacted to ensure safety by mandating the replacement of any landing gear emergency hand pump with a serial number within the specified range, as these components were found to be machined incorrectly and may fail in an emergency situation. The objective of this directive is to mitigate risks by requiring the replacement of defective components and ensuring compliance within a specified timeframe. This measure was introduced by the Civil Aviation Safety Authority to maintain the safety standards required for aviation operations, ensuring that any affected aircraft are equipped with reliable emergency hand pumps.
Scope and Application
The Civil Aviation Safety Authority (CASA) has issued an Airworthiness Directive (AD) under the Civil Aviation Regulations 1998, specifically targeting the Beechcraft 300 Series aeroplanes. The directive applies to all Raytheon (Beechcraft) B300 model aeroplanes, regardless of their serial numbers, to address a critical safety concern associated with the landing gear emergency hand pump. The directive mandates that any landing gear emergency hand pump with a part number 101-388007-3 and a serial number within the range 2702 through 2833 must be replaced. This requirement is based on evidence that these specific components were manufactured with defects that could lead to failure in an emergency situation. The directive, which became effective on 27 September 1999, requires compliance within 25 hours of time in service from the effective date. Compliance can be demonstrated if the aircraft maintenance records confirm that the serial number of the emergency hand pump fitted falls outside the range of affected components. The directive aligns with the US Federal Aviation Administration's AD 99-18-15 Amdt 39-11281 dated 23 August 1999, reflecting a coordinated international safety effort.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the requirements for the airworthiness of aircraft, including the mandatory compliance with Airworthiness Directives (ADs). Under this section, the AD/BEECH 300/14 (paragraph 39-105.1) mandates the replacement of the landing gear emergency hand pump on all Raytheon (Beechcraft) B300 model aeroplanes with serial numbers in the specified range (section 39-105.1(1)). The directive applies to all Beechcraft 300 series aeroplanes and requires the replacement of any landing gear emergency hand pump, part number 101-388007-3, with a serial number in the range 2702 through 2833. The requirement is to ensure these components are replaced to avoid potential malfunctions during emergency situations.
Operators of Beechcraft 300 series aeroplanes must adhere to the directive by replacing the specified emergency hand pump within 25 hours time in service from the effective date of the directive (section 39-105.1(2)). Compliance can be demonstrated by ensuring the aircraft maintenance records identify that the serial number of the emergency hand pump fitted falls outside the affected range. This ensures that the defective components are identified and replaced in a timely manner, maintaining the airworthiness of the aircraft.
Failure to comply with the AD/BEECH 300/14 may result in significant safety risks, as the defective components could lead to a failure of the emergency hand pump during critical situations. The Civil Aviation Safety Authority (CASA) enforces these regulations rigorously, and non-compliance could lead to enforcement actions. The penalties for not adhering to the airworthiness directives can include fines, operational restrictions, or even grounding of the aircraft until compliance is achieved. The exact penalties would depend on the severity and circumstances of the non-compliance, but they can be substantial, reflecting the importance of maintaining air safety standards.
