To prevent loss of engine oil and possible failure of the engine, accomplish the following: (a) Visually inspect the oil pressure gauge hose assembly at the engine to determine whether the type of hose assembly installed is P/N B7071. (See Fig. 1) (1) If the oil pressure hose assembly is not of the type illustrated in Figure 1, no further action in accordance with this AD is required. (2) If the oil pressure hose assembly is of the type illustrated in Figure 1, prior to the next flight, replacewith a new P/N B7071 hose assembly identified by Taylorcraft with a "T" stamped on one of the wrenching flats on one of the hose assembly brass fittings. (b) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished.
