Applies to All Models Temco D-16 and D-16A Aircraft. Compliance required within 25 hours' time in service following the effective date of this AD and at each periodic inspection thereafter. (a) Inspect the flap and landing gear actuating cylinders for cracks. If any cracks appear, the cylinder must be replaced. (b) Determine, by means of a hydraulic gage, that the hydraulic system pressure relief valve is adjusted to 1125 + 25, -0 p.s.i. Excessive pressures could cause damage to the components of the system. (c) Unless already installed, install hydraulic fluid restrictors in the nose gear lines, Serial Numbers 1271 and subsequent, main gear lines, Serial Numbers 1790 and subsequent, and flap lines, all serial numbers. (d) Inspect the linkage adjustments of the landing gear bungee springs and the flap stops and determine that they have been properly adjusted in accordance with appropriate service manuals.
