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.
Pacific Aerospace Corporation Cresco Series Aeroplanes
AD/CRESCO/3 Elevator Tip Rib 11/2002 DM
Applicability: Cresco 08-600 series aircraft that have not been modified by either PAC/CR/0251 or PAC/CR/0406.
Requirement: Inspect in accordance with Pacific Aerospace Corporation Service Bulletin PACSB/CR/030 Issue 2.
If cracks are found, before further flight, repair in accordance with the Requirement document.
Note 1: Incorporation of modification specified in SB PACSB/CR/030 is considered terminating action for the repeat inspection requirement of this Directive.
Note 2: NZ CAA AD DCA/CRESCO/3 refers.
Compliance: Within 50 hours time in service after 4 September 2002. Thereafter at intervals not to exceed 100 hours time in service.
This Airworthiness Directive becomes effective on 4 September 2002.
Background: Field experience indicates that cracking of the components of the elevator tip (end
rib- mass balance, elevator rib, or spar-outer) can occur. Such cracking of the elevator tip components could result in loss of the elevator tip, with a resultant reduction in pitch control.

Overview
The Civil Aviation Regulations 1998, specifically Part 39, was enacted to establish and regulate the standards for ensuring the safety and airworthiness of aircraft in Australia. This legislative instrument aims to address identified safety concerns and ensure that aircraft meet the required safety standards. The Civil Aviation Safety Authority (CASA) issued the Airworthiness Directive (AD/CRESCO/3) for the Pacific Aerospace Corporation Cresco Series Aeroplanes on 4 September 2002, in response to reports of cracking in the elevator tip components, which could lead to a loss of pitch control. The directive requires that Cresco 08-600 series aircraft that have not been modified by either PAC/CR/0251 or PAC/CR/0406 be inspected in accordance with Pacific Aerospace Corporation Service Bulletin PACSB/CR/030 Issue 2. If cracks are found, repairs must be made before further flight in line with the requirement document. The objective of this directive is to ensure the safe operation of the affected aircraft by addressing the identified safety issue.
Scope and Application
The Airworthiness Directive (AD) pertains specifically to Cresco 08-600 series aircraft manufactured by Pacific Aerospace Corporation, which have not undergone modifications as outlined in the Pacific Aerospace Corporation Service Bulletins PAC/CR/0251 or PAC/CR/0406. This AD applies to the elevator tip rib of these aircraft and is issued by the delegate of the Civil Aviation Safety Authority (CASA) to address the safety concern identified in the background section. The directive mandates that an inspection be conducted in accordance with Pacific Aerospace Corporation Service Bulletin PACSB/CR/030, Issue 2. Should cracks be detected during this inspection, the directive requires that they be repaired before further flights, following the instructions provided in the aforementioned service bulletin. Notably, the incorporation of the modification specified in this service bulletin is considered to be the terminating action for the repeat inspection requirement stipulated in this directive. This AD became effective on 4 September 2002 and is applicable within 50 hours of time in service following that date, with subsequent inspections mandated at intervals not exceeding 100 hours of time in service.
Key Provisions
The Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) under section 39.1(1) of the Civil Aviation Regulations 1998 (CAR 1998) is targeted at Cresco 08-600 series aircraft that have not undergone modifications specified in PAC/CR/0251 or PAC/CR/0406. This AD, AD/CRESCO/3, mandates that inspections of the elevator tip ribs be carried out in accordance with the instructions set out in Pacific Aerospace Corporation Service Bulletin PACSB/CR/030 Issue 2. If any cracks are identified during the inspection, the aircraft must be repaired before further flight as per the requirement document. Notably, the incorporation of modifications as per SB PACSB/CR/030 is considered to be the terminating action for the repeat inspection requirement of this directive. Compliance with this AD must occur within 50 hours of time in service after the directive's effective date of 4 September 2002, and thereafter at intervals not exceeding 100 hours of time in service.
The obligations imposed by this AD require aircraft operators to ensure that the specified inspections and repairs are conducted as per the outlined procedures. This includes adherence to the Pacific Aerospace Corporation Service Bulletin PACSB/CR/030 Issue 2 for the inspection process. Operators must also ensure that any identified cracks are repaired before further flight. Additionally, the directive necessitates that these inspections and repairs be documented and maintained in the aircraft’s maintenance records.
Failure to comply with the requirements of this AD may result in severe consequences. Under the Civil Aviation Act 1988, non-compliance can lead to civil penalties, including fines and potential criminal charges. The specific penalties can vary based on the severity of the breach, but they may include substantial fines and imprisonment for more severe violations. The exact penalties are determined by the courts and are subject to the discretion of the relevant authorities, but the potential repercussions underscore the importance of adhering to the AD’s requirements.
