Narrative:

After completing a VFR practice ILS approach to runway 7, during the missed approach from over the approach lights at 200+ ft AGL and climbing (I was the safety pilot), I observed a single engine high wing cessna to our left over runway 20. We were cleared for the option runway 7 from a 3 mi final. These runways cross near the approach end of runway 7 and departure end of runway 20. Since this cessna was about 1/4 mi to my left and at approximately the same altitude, I took control of the aircraft from the pilot under the hood, reduced power and lowered the nose to ensure we would pass well clear beneath the climbing cessna. I believe the cessna passed above and behind us. Apparently, the local controller at the tower did not ensure the cessna would cross the runway 20 threshold after we passed the intersection of the 2 runways. If the cessna was cleared for the low approach, or the controller cleared the cessna for takeoff or touch-and-go before we passed the intersection, this was an error of judgement in anticipating intersecting runway separation after issuing clrncs. Local controller failed to ensure intersecting runway separation for 2 aircraft, each using different runways at the same aerodrome. Controllers need to exercise greater vigilance to ensure runway separation, when traffic conditions increase in volume and complexity.

Title: PA28 ON ILS GAR CONFLICTS WITH TFC USING INTERSECTING RWY UNDER TWR CTL AT PHF.

Narrative: AFTER COMPLETING A VFR PRACTICE ILS APCH TO RWY 7, DURING THE MISSED APCH FROM OVER THE APCH LIGHTS AT 200+ FT AGL AND CLBING (I WAS THE SAFETY PLT), I OBSERVED A SINGLE ENG HIGH WING CESSNA TO OUR L OVER RWY 20. WE WERE CLRED FOR THE OPTION RWY 7 FROM A 3 MI FINAL. THESE RWYS CROSS NEAR THE APCH END OF RWY 7 AND DEP END OF RWY 20. SINCE THIS CESSNA WAS ABOUT 1/4 MI TO MY L AND AT APPROX THE SAME ALT, I TOOK CTL OF THE ACFT FROM THE PLT UNDER THE HOOD, REDUCED PWR AND LOWERED THE NOSE TO ENSURE WE WOULD PASS WELL CLR BENEATH THE CLBING CESSNA. I BELIEVE THE CESSNA PASSED ABOVE AND BEHIND US. APPARENTLY, THE LCL CTLR AT THE TWR DID NOT ENSURE THE CESSNA WOULD CROSS THE RWY 20 THRESHOLD AFTER WE PASSED THE INTXN OF THE 2 RWYS. IF THE CESSNA WAS CLRED FOR THE LOW APCH, OR THE CTLR CLRED THE CESSNA FOR TKOF OR TOUCH-AND-GO BEFORE WE PASSED THE INTXN, THIS WAS AN ERROR OF JUDGEMENT IN ANTICIPATING INTERSECTING RWY SEPARATION AFTER ISSUING CLRNCS. LCL CTLR FAILED TO ENSURE INTERSECTING RWY SEPARATION FOR 2 ACFT, EACH USING DIFFERENT RWYS AT THE SAME AERODROME. CTLRS NEED TO EXERCISE GREATER VIGILANCE TO ENSURE RWY SEPARATION, WHEN TFC CONDITIONS INCREASE IN VOLUME AND COMPLEXITY.
