OPINION

Geovani Davila appeals a final judgment of conviction from the United States District Court for the Middle District of Pennsylvania. On June 20, 2001, Davila pled guilty to one count of conspiracy to distribute and to possess with intent to distribute heroin. On February 8, 2002, Davila was *937 sentenced to 384 months imprisonment. Davila appeals, contending that the District Court erred in accepting his guilty plea without first establishing a factual basis for a conspiratorial agreement in violation of F.R.Crim.P. 11(f). Davila did not bring this alleged error to the attention of the District Court.

We exercise appellate jurisdiction pursuant to 28 U.S.C. § 1291. We review unpreserved challenges to plea colloquies for plain error. See e.g. United States v. Vonn, 535 U.S. 55, 58-59, 122 S.Ct. 1043, 152 L.Ed.2d 90 (2002).

Davila argues that the District Court erroneously accepted his guilty plea without establishing a valid factual basis to support the conspiracy count as required by F.R.Crim.P. 11(f). To meet the plain error test. Davila must prove that (1) an error was committed, (2) the error was plain, (3) the error effected Davila’s substantial rights, and (4) the Court of Appeals should exercise its discretion to correct the error because it seriously effects the fairness, integrity or reputations of the judicial proceedings. See e.g. United States v. Syme, 276 F.3d 131, 143 (2002) citing United States v. Olano, 507 U.S. 725, 734, 113 S.Ct. 1770, 123 L.Ed.2d 508 (1993).

Davila contends that the “plain error” here is the lack of a factual basis for a “conspiratorial agreement.” F.R.Crim.P. 11(f) requires that “notwithstanding the acceptance of a plea of guilty, the court should not enter a judgment ... without making such inquiry as shall satisfy that there is a factual basis for the plea.” However, the court does not need to be convinced that a defendant is guilty beyond a reasonable doubt when accepting a guilty plea, only that there is sufficient evidence to justify the reaching of such a conclusion. See United States v. Cefaratti 221 F.3d 502, 509 (3d Cir. 2000).

Here, during Davila’s guilty plea colloquy, the District Court recited and explained the conspiracy charge to Davila and asked if he knowingly and voluntarily agreed to plea guilty. Davila affirmed that he did. Further, the District Court explained the legal definition of conspiracy to Davila and asked if he understood and agreed to plea to conspiracy and the unlawful acts of distributing heroin. Davila again affirmed. Finally, the District Court asked the government to present the facts that supported the charged offense. The government did so and the District Court determined that the guilty plea was supported by a basis in fact and contained all elements of the charged offense. We find no error, muchless plain error. Davila has failed to meet his burden.

For the above reasons, we will affirm the judgment of the District Court.
