Identified on the Y93 table by Sale_reported = “Y” - or - Active_flag = “I” . Either of these conditions render the operator uncontactable by CAWIS and these operators are exempted from both AD and AAIR distribution until such time as legitimate contact data is re-established in CCARCS.
Amateur Built / Ultralight aircraft
These are aircraft with flight authority F,H or I. These are not required to comply with ADs and are not included in distributions (exception: if the aircraft is using some kind of type-approved engine or propeller, they will appear on the distribution list )
Owner Maintenance aircraft
Flight Authority = “C” . These are usually older aircraft that have become uneconomical to maintain. All models for these aircraft are suffixed with an “X” and thus, do not appear in AD distributions. The onus is on the operator to look up their A/E/P models on the public web search facility and inspect/maintain their own aircraft.
Cancelled Airworthiness Directives
When an AD is cancelled it needs to be :
have the cancelled indicator ticked on the AD modify page
untick all “document available” links
The word cancelled is to appear at the beginning of the subject -or- cancelled by in the event that it has been replaced by a new AD.
If cancelled by a new AD, the Country Code/Ad number needs to be filled into the appropriate AD fields, and included in the AD subject
Ideally, cancelled ADs should be deleted from the External/Internal web folder(s), but CAWIS users cannot access either. So the practice was created to overwrite old documents using “dummy” docs having the same name ( sample DUMMY AD ) as outlined in TFS ITEM #13712. The user’s concern here was that cancelled and/or superseded versions of old ADs were still available to the public through Google search, despite no longer being available using AD web.
