Where should placards be placed after completing a deferral?

• A. On the top copy and second copy of 86-100
• B. On the left column of form DMI
• C. On or near inop unit or switch
• D. In the flight crew bags

Answer: (A)

Placards go on the official deferral paperwork so the deferral is clearly tied to the aircraft’s records and visible to those who must see it. In this case, that means placing the placards on the top copy and the second copy of Form 86-100. This ensures both the flight crew and maintenance personnel have immediate access to the deferral information and know which item is inoperative and under the deferral. Putting placards on a different form, on or near the unit itself, or in a crew bag would not guarantee the deferral record stays with the item or is readily seen by the people who need it, which is why the top and second copies of 86-100 are the correct places.
