The airworthiness directive
47-36-02 DOUGLAS: (Was Mandatory Note 2 of AD-3L-1.) Applies to A-26B and A-26C Aircraft.
Compliance required prior to operation in cold weather and not later than next engine overhaul.
To preclude collapse of the oil screen during cold weather starting, replace oil screen assembly No. 51887 with oil screen assembly Nos. 51887M or 107547. P/N 51887 may be reworked to P/N 51887M by incorporating reinforcing spring No. 107542 and adding the letter "M" to the part number.
