COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.1 (1) of CAR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
Boeing 737 Series Aeroplanes
AD/B737/193 Flight Deck Emergency Windows 11/2002
Applicability: Model 737-600, -700, and -800 series aircraft, line numbers 1 through 144. Requirement: Action in accordance with the technical requirements of FAA AD 99-26-10 Amdt 39-
11469.
Note: Boeing Alert Service Bulletin 737-56-1011 refers.
Compliance: As specified in the Requirement document, with a revised effective date of 31 October 2002.
This Airworthiness Directive becomes effective on 31 October 2002.
Background: The FAA received reports that flight deck emergency exits (number 2 windows) were found frozen shut after landing. This Directive requires certain actions to prevent water accumulation in the lower corners of the flight deck emergency exits, which can freeze and prevent the exits from being used during an emergency evacuation.

Overview
The Civil Aviation Regulations 1998, which were enacted by the Australian Parliament, are a comprehensive set of rules governing civil aviation within Australia. Specifically, Part 39 of these regulations, titled "Civil Aviation Safety Authority Schedule of Airworthiness Directives", addresses various safety concerns and requirements for aircraft and aeronautical products. One such directive, AD/B737/193, was issued to address a problem identified with the Boeing 737 Series aeroplanes, particularly models 737-600, -700, and -800. The directive was enacted to ensure the safety of the aircraft by addressing the issue of flight deck emergency windows freezing shut after landing, which could potentially hinder emergency evacuations. This Airworthiness Directive was issued by a delegate of the Civil Aviation Safety Authority (CASA), with the aim of preventing water accumulation in the lower corners of the emergency exits, which could subsequently freeze and obstruct the exits. The directive was effective from 31 October 2002.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 105, includes Airworthiness Directives (ADs) issued by the Civil Aviation Safety Authority (CASA) to ensure the safety of aircraft and aeronautical products within Australian jurisdiction. This particular AD, AD/B737/193, applies to Boeing 737 Series Aeroplanes, specifically model 737-600, -700, and -800 series aircraft, line numbers 1 through 144. The directive mandates corrective action to address a reported issue where flight deck emergency exits (number 2 windows) were found frozen shut after landing due to water accumulation in the lower corners. Compliance with this AD requires adherence to the technical requirements outlined in FAA AD 99-26-10 Amdt 39-11469 and must be carried out by the specified effective date. This AD was issued to prevent such incidents during emergency evacuations and was published in the Commonwealth of Australia Gazette on 9 October 2002. The directive is a critical component of the regulatory framework governing civil aviation safety, ensuring that aircraft remain airworthy and safe for operation within Australian airspace.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39, Section 105, outlines an Airworthiness Directive (AD) that is applicable to certain Boeing 737 series aircraft (sections 1-4). This AD, designated AD/B737/193, addresses flight deck emergency windows on models 737-600, -700, and -800 series, specifically for line numbers 1 through 144. The directive requires actions to be taken to prevent water from accumulating and freezing in the lower corners of the flight deck emergency exits, which could hinder emergency evacuations (section 4). The required action must comply with the technical requirements outlined in the FAA AD 99-26-10 Amdt 39-11469, as referenced in Boeing Alert Service Bulletin 737-56-1011 (section 4). Compliance with this AD must be achieved by 31 October 2002, as specified in the requirement document, with the AD becoming effective on the same date (section 5).
Entities governed by this AD, such as aircraft operators and maintenance providers, are obligated to ensure that the specified actions are implemented on the applicable Boeing 737 aircraft models within the stipulated timeframe (section 5). This includes reviewing and, if necessary, modifying the flight deck emergency exits to prevent water accumulation and freezing. Maintenance records must be updated to reflect compliance with the directive. These obligations are essential to maintaining the airworthiness and safety of the aircraft involved.
Failure to comply with the Airworthiness Directive may result in significant legal and safety repercussions. The Civil Aviation Safety Authority (CASA) may take enforcement actions against non-compliant entities, which could include fines, suspension or revocation of air operator certificates, and other administrative penalties (section 6). Additionally, non-compliance could lead to the grounding of affected aircraft until the necessary actions are completed, potentially resulting in substantial operational disruptions. Civil or criminal liability may also arise if non-compliance is found to have contributed to safety incidents or accidents.
