Continuing Airworthiness Notices

A Continuing Airworthiness Notice (CAN) is intended to alert, educate, and make recommendations to the aviation community. A CAN contains non-regulatory information and guidance that does not meet the criteria for an Airworthiness Directive (AD). The inspections and practices described in a CAN must still be carried out in accordance with the applicable NZCAR Parts 21, 43 and 91. CAN numbering is by ATA Chapter and a serial number for the next CAN in that ATA Chapter.

Cargo Hook Systems – Inspection and Maintenance Requirements. To advise operators and maintainers of cargo hook systems that compliance with manufacturer provided Instructions for Continuing Airworthiness (ICA) is required to ensure the hook system is kept in an airworthiness condition. This Continuing Airworthiness Notice (CAN) focusses on wear and damage found on Onboard Systems Cargo Hooks.  Cargo hook systems from other manufacturers (e.g. Breeze Eastern) suffer the same wear and damage as identified in this CAN. All cargo hook systems must be maintained in accordance with the applicable manufacturer ICA. 05-006 (PDF 232 KB) 01 Mar 2017
Measuring tapes used to determine the centre of gravity (CG), and the weight and balance of an aircraft. This Continuing Airworthiness Notice (CAN) is prompted by a report received by the CAA of finding a measuring tape with two measuring scales printed on it. One scale is marked in mm, and a second scale marked in units of 1/33m, which was mistaken to be 1” increments. Aircraft maintainers must be familiar with the units of measurement marked on the measuring tape when determining the weight and balance of an aircraft. 08-001 Revision 1 (PDF 110 KB) 21 Oct 2016

Applicability Subject CAN No. Issue Date
Connecting rod small end bushes with Lycoming P/N LW-13923. Affected engines may include locally overhauled engines, as well as factory new/reworked engines. This Continuing Airworthiness Notice (CAN) is prompted by local and Australian reports of finding failed connecting rod small end bushes with Lycoming P/N LW-13923. Affected small end bushes tend to work loose in service and migrate out the connecting rod small end bore.
As the small end bushes migrate from the connecting rod small end bore they are held in position by the inner piston wall. Wear slowly begins to erode the length of the bush. This initial wear produces small particles of bronze which should be evident in the engine oil filter. Once the wear has progressed to allow the bush to significantly egress from the bore, the lack of surface area and the abnormal loading will result in the bush breaking up.
Furthermore, the reduction in the length of the bush will result in an insufficiently supported piston pin, which could cause failure of the connecting rod small end bore, and result in a catastrophic engine failure.

Transport Canada - Civil Aviation Safety Alerts (CASA), Service Difficulty Alerts, and Service Difficulty Advisories

Subject Date
TP 6980E

Feedback is published quarterly by the Continuing Airworthiness Division of Transport Canada, informing the aviation community of reported day-to-day problems that affect aircraft airworthiness in Canada. Issue 03/2016 has recently been published.

28 Feb 2017
CASA 2016-14

The purpose of this Civil Aviation Safety Alert (CASA) is to raise awareness of the possibility of cracking and potential
failures of control columns installed on Piper PA-28 series of aircraft.

09 Dec 2016
CASA 2016-11

The purpose of this CASA is to emphasize the importance to thoroughly examine the engine mount legs on Bell model 206L-series helicopters and replace deteriorated parts.
Operators have submitted Service Difficulty Reports noting that engine mount legs have been found corroded and/or cracked. On the 206L-series helicopters, there are six legs that hold the engine in place. In some cases the damage was not obvious because a wiring or tubing support clamp was installed on the leg, hiding the damage. In some cases, there have been reports of significant corrosion-related damage on the inside of the part where it would not be visible during inspection.
Bell Helicopter Textron Canada issued Operation Safety Notice 206L-15-51 to owners and operators of model 206L-1 and 206L-3 helicopters to highlight the criticality of inspection of the engine mount legs. That document also informs operators that Bell Helicopter has introduced engine mount legs made of CRES (stainless steel), noting that these parts have improved resistance to corrosion. It concludes by clarifying what components of the legs can be replaced and noting some important considerations that apply during inspection and reassembly.
Transport Canada and another civil aviation authority have obtained information that the CRES parts have also been reported cracked and corroded, and are not immune to degradation.
