## The airworthiness directive

66-19-02 CESSNA: Amdt. 39-270 Part 39 Federal Register August 4, 1966. Applies to Models 210 and 210A Airplanes, Serial Numbers 616, 618, 57001 through 57575, and 21057576 through 21057840.

Compliance required within the next 25 hours' time in service after the effective date of this AD, unless already accomplished.

To prevent engine power failures caused by the loss of fuel flow resulting from the uncovering of the fuel tank outlet during landing approaches and prolonged slips, install an operating limitation placard, reading as follows, adjacent to the fuel gauges:

"Avoid landing approach in red arc and over 30 seconds slips under 1/2 tank (Reference Owner's Manual)".

(Cessna Service Letter 65-39 pertains to this subject.)

## NTSB investigations that cite this AD (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
