The maverick paceman hit fellow fast bowler Mohammad Asif with a bat during a practice session three days before the start of the event in South Africa and was sent home a day after the incident.
Akhtar faces a fine of 500,000 rupees and a five one-day internationals ban if found guilty of misconduct.
"Akhtar is asked to appear before the committee on October 6 to record his statement," Shafqat Naghmi head of Pakistan Cricket Board disciplinary committee said.
The other two members of the committee are Zakir Khan and Nadeem Akram.
The committee will not complete its investigation before October 8 -- ruling out any chance of Akhtar featuring in the two Tests against visiting South Africa.
Akhtar was not considered for selection in the Pakistan team for the first Test starting here from Monday. The second Test will be played in Lahore from October 8.
Asif and allrounder Shahid Afridi, who saw the incident, have also been summoned to attend the hearing, said Naghmi.
