Darrel G. Jones, federal prisoner # 30209-048, filed a 28 U.S.C. § 2255 mo *404 tion, challenging his convictions for possession with intent to distribute cocaine and possession of a firearm during a drug trafficking offense and his aggregate 248-month sentences. The district court found that Jones’s § 2255 motion was successive and transferred the case to this court for a determination whether Jones was entitled to authorization to proceed. Jones currently seeks a certificate of appealability (COA) to appeal the district court’s denial of his motion for reconsideration of this transfer order.

If necessary, this court must examine the basis of its jurisdiction sua sponte. Mosley v. Cozby, 813 F.2d 659, 660 (5th Cir. 1987). The order denying Jones’s motion to reconsider the order transferring his § 2255 motion to this court is a non-appealable interlocutory order. See 28 U.S.C. §§ 1291, 1292(a), (b); Fed.R.Civ.P. 54(a), 59(e); Brinar v. Williamson, 245 F.3d 515, 516-18 (5th Cir. 2001). This court is without jurisdiction to consider Jones’s request for a COA. Consequently, the motion for a COA is DENIED, and the APPEAL IS DISMISSED for lack of jurisdiction.
