## Discrepancy

L/G WOULD NOT RETRACT USING EITHER SYS 1 OR 2.  PERFORMED SERVICE OF LT BOOGIE PITCH DAMPER WITH NITROGEN PER AMM 12-12-32-0 PARAGRAPH 10.  FOUND THAT PITCH DAMPER ONLY HAD A 400 PSI PRECHARGE.  CURRENT LIMITS PER CHART FIG 11 IS 1300 PSI.  RECHARGED PITCH DAMPER TO SERVICABLE LIMITS PER AMM 12-12-32-0.  DECAY CHECK WITH NO PRESSURE DROP OVER A ONE HOUR PERIOD OF TIME PER SMP.  A/C OK FOR CONTINUED SERVICE.
