Annual Airworthiness Information Reports
Annual Airworthiness Information Reports (AAIRs) are a means by which Transport Canada (TC) collects essential airworthiness data from Canadian registered aircraft owners. This data is used to ensure accurate and thorough distribution of Airworthiness Directives (ADs) and Civil Aviation Safety Alerts (CASAs) to all applicable Canadian registered aircraft owners, monitor the activity of the Canadian aircraft fleet and calculate accident and incident statistics.
Pursuant to Part V, Subpart 1 of the Canadian Aviation Regulations (CAR) and Standard 501, the owner of every Canadian registered aircraft, other than an ultra-light aeroplane, is required to submit to TC a completed AAIR no later than a specified due date on an annual basis. Owners who fail to submit the AAIR are liable to a monetary fine.
Presently, a paper copy of the AAIR is mailed to each aircraft owner approximately 2 months prior to the due date. If the data printed on the form is incorrect and/or if the contact information has changed, the aircraft owner is required to update the information on the form. They must also indicate the number of hours flown during the last calendar year and the Time Since New (TSN) as of December 31st. Finally, for aircraft which are not operated pursuant to CAR IV or CAR VII, the owner is to provide the date of the most recent annual or 100 hour inspection, and the name of the person who performed it.
As of January 31st, 2013, all AAIRs are now to be mailed to the Transport Canada office in Ottawa or scanned and sent by e-mail to firstname.lastname@example.org. More preferably AAIRs can be completed online through the TC Continuing Airworthiness Web Information System (CAWIS) website. Consolidated fleet reports can be completed instead of completing individual AAIRs, however aircraft owners must remember to send the report to Transport Canada prior to the due date as these cannot be completed online.
In an effort to reduce our environmental footprint, Transport Canada is working towards making the necessary enhancements to CAWIS so that AAIRs can eventually be sent to aircraft owners by e-mail. If you have not provided your e mail address to Transport Canada, you are encouraged to do so by sending the information to email@example.com. You can also use this e-mail address to send us questions or concerns related to the AAIRs program or any other continuing airworthiness topics.
All regulatory requirements and procedures of the AAIR are provided in CAR 501 (http://www.tc.gc.ca/eng/civilaviation/regserv/cars/part5-subpart1-1771.htm) and Standard 501 (http://www.tc.gc.ca/eng/civilaviation/regserv/cars/part5-standards-standard501-1952.htm). Instructions for completing the AAIR are supplied with each copy of the reporting form and on the website.
Infrequent Use of Engines & Use of 3rd Generation Oils
Pratt & Whitney Canada (P&WC) has received reports of loss of engine oil pressure occurring on two separate aeroplanes.
Investigation into these events revealed that these engines had been inactive for extended periods of time. Although periodic engine maintenance ground run-ups had been carried out, it was determined that the engine run-ups may not have been long enough to detect any engine deterioration. P&WC have now added additional instructions to the applicable engine manuals to address the above problem.
The use of 3rd generation engine oils has proven to be beneficial because of their thermal stability and resistance to oxidation at high temperatures. This is found to be factual provided that these engine(s) are utilized in normal and continuous operations. However, over a period of time, these 3rd gen oils can cause degradation and hardening of the engine seals. When preserved engines are being re-activated, particular attention should be given to the condition of seals especially in the area of the accessory gear box (AGB) pad.
Transport Canada Comments:
Transport Canada Civil Aviation (TCCA) recommends that owners, operators and other responsible persons familiarize themselves with and closely follow the instruction detailed in P&WC Service Information Letter (SIL) PW500-045 dated October 24 2011.
