Table 29-1. Allowable leakage for in-service hydraulic components
Component Function Leak Type Leakage Rate (Max)
Flight
Rod Seal D 1 drop/20 full stroke cycles
Controls
Rod Seal S-D 1 drop/15 minutes
Actuators
End Cap S 2 drops/day
Valve Input D 1 drop/5 cycles
S-D 1 drop/5 minutes
Pressure switch S-D 1 drop/5 minutes
Valve body (weep holes)
S-D 1 drop/5 minutes
Pumps
Output shaft D 8 drops/minute
S-D 1 drop/minute
Housing (mating surface)
S 2 drops/day
Valves
Body (weep holes) S 2 drops/day
Manual stem D 1 drop/5 cycles
S-D 1 drop/15 minutes
Dump valve S 2 drops/day
By-pass Check Valve
D 2 drops/25 cycles
S None at static pressure of 5 to
1000 PSI
Fittings
Flared or flare-less S None
Compression seals S 1 drop/30 min. (less if readily
accessible)
NOTES:
1. Leak Types: D = Dynamic
S = Static
S-D = Static leakage through dynamic seal
2. Approximately 20 drops = 1 cubic centimeter.
3. Components in static condition, as in parked aircraft, are allowed maximum leakage of two drops per
seal or packing per day.
