Summary

We propose to adopt a new airworthiness directive (AD) for certain Robinson Helicopter Company (Robinson Helicopter) Model R66 helicopters. This proposed AD would require inspecting the oil tank outlet's fitting color. If the fitting is blue, this proposed AD would require replacing the tank with an oil tank that lacks a blue fitting. This proposed AD also would require determining the revision letter on the ink stamp, and installing an oil tank angle based on that determination. This proposed AD is prompted by reports of broken oil tank internal baffles. The actions of this proposed AD are intended to correct an unsafe condition on these products.

The agency’s own summary, as published.
