Piper PA-44-180 SEMINOLE Maintenance Manual page 236

NO FIELD RECHARGE OR SERVICING FACILITIES, MANUFA C T U R E R
WILL RECHARGE OR SERVICE AND RETURN FOR A SERV I C E
CHARGE.
The required service checks are as follows:
1. Annual weighing to determine if a weight loss exist. (Limitation is ± 2 ounces)
Ambient temperature has a direct relationship to the pressure displayed on the gauge.
The pressure gauge has temperature extremes noted on the scale. If any questions
exist to the effects of the temperature, they may be eliminated by allowing the unit to
remain at room temperature, then reading the gauge. (70°F)
2. 6 year tear down inspection.
3. 12 year hydro-static test.
The manufacturer recommends an initial weighing to determine a base line weight,
and then a weight check every six months to establish a weight loss pattern. This
supercedes the annual weight check.
All servicing shall be performed by the manufacturer.
