SE\nWashington. DC 20590\nSEP 0 1 2011\nMr. Douglas Svoboda\nFlightpath Services, Inc.\n500 Hollister Road\nTeterboro, NJ 07801\nRef. No. 11-0131\nDear Mr. Svoboda:\nThis responds to your letter requesting clarification of the cylinder requalification\nprovisions under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).\nSpecifically, you ask whether all cylinders must be requalified before refilling or just those\ncylinders where requalification is due or past due. Additionally, you ask if requalification\nis required if a cylinder installed in an aircraft rapidly discharges (e.g., emergency inflation\ncylinder on a life raft) before it can be returned to service.\nIn accordance with § 180.205(c) of the HMR, a cylinder may be requalified at any time\nbefore or during the month and year the requalification is due. A cylinder filled before the\nrequalification becomes due may remain in service until it is emptied. A cylinder with a\nspecified service life or past its requalification date may not be refilled and offered for\ntransportation after its authorized service life has expired or, it is requalified, respectively.\nFor a cylinder installed in an aircraft that rapidly discharges, requalification is required if\nthe conditions specified in § 180.205(d) are met. Specifically, a cylinder must be tested\nand inspected, without regard to any other periodic requalification requirements, prior to\nfurther use if: (1) The cylinder shows evidence of dents, corrosion, cracked or abraded\nareas, leakage, thermal damage, or any other condition that might render it unsafe for use\nin transportation; (2) The cylinder has been in an accident and has been damaged to an\nextent that may adversely affect its lading retention capability; (3) The cylinder shows\nevidence of or is known to have been over-heated; or (4) The Associate Administrator\ndetermines that the cylinder may be in an unsafe condition.\nI trust this satisfies your inquiry. Please contact us if we can be of further assistance.\noj,~'\"\n1\\ T.

I need a interpretation in\nwriting to clear up this matter.\nAlso is there any regulation requiring requalification after a rapid discharge, such as a\nemergency inflation cylinder on a life raft.\nName: Douglas Svoboda\nOrganization: Flightpath Services, Inc.\nEmail: dsvoboda@flightpathservices.com\nAddress: 500 Hollister Rd.\nCity: Teterboro\nZip Code: 07801\nPhone: 201-489-7950\nFAX: 201-489-8537\n1","truncated":false,"body_characters":3658}
