In my opinion, the trench drain IAM proposed is acceptable since wing span will prevent aircraft from rolling over the trench grate.

Can you send me a drawing that shows the location of the proposed trench drain? Wingtip dimensions may allow for less than aircraft-rated trench drain.

Frank,
IAM poured the concrete to the incorrect grade right in front of the T-hangars on the west side of the Planesmart ramp causing the drainage to go back into the T-hangar as opposed to
draining down the ramp space. I suggested a trench drain as a possible solution. Attached is the trench drain IAM recommended using. I just wanted to check with you and see if it
was capable of supporting any aircraft that would use that T-hangar or if there was another trench drain that you would recommend.
Thanks,
