Patrick Carlos Britton, federal prisoner number 24975-034, was convicted of conspiracy to possess with intent to distribute cocaine and was sentenced to 121 months of imprisonment. Britton seeks a certificate of appealability (COA) to appeal the district court’s order transferring his successive 28 U.S.C. § 2255 application to this court.

We must examine the basis of our jurisdiction sua sponte if necessary. Mosley v. Cozby, 813 F.2d 659, 660 (5th Cir. 1987). An order transferring a successive 28 U.S.C. § 2255 application to the court of appeals is a non-appealable interlocutory order. See Brinar v. Williamson, 245 F.3d 515, 516-18 (5th Cir. 2001). This court is without jurisdiction to consider Britton’s appeal. Accordingly, Britton’s motion for a COA is DENIED, and the appeal is DISMISSED for lack of jurisdiction.

MOTION DENIED; APPEAL DISMISSED.
