Case study: A Cessna 172I with inop flap position indicator.
For the aircraft to remain airworthy, must the inop gauge be placarded and the journey log endorsed with a corresponding maintenance release??
According to CAR 605.10(2):
Where a minimum equipment list has not been approved in respect of the operator of an aircraft and the aircraft has equipment, other than the equipment required by subsection (1), that is not serviceable or that has been removed, no person shall conduct a take-off in the aircraft unless
(a) where the unserviceable equipment is not removed from the aircraft, it is isolated or secured so as not to constitute a hazard to any other aircraft system or to any person on board the aircraft;
(b) the appropriate placards are installed as required by the Aircraft Equipment and Maintenance Standards; and
(c) an entry recording the actions referred to in paragraphs (a) and (b) is made in the journey log, as applicable.
I am unable to identify the required standard regarding the requirement for the installation of placards as it involves unserviceable equipment. 625.10 does not mention placards.
Any thoughts and comments regarding this topic would be most welcome. Please quote the CAR's where applicable to support the airworthiness requirements.
Best,
